  • Letter to my MPs on Cyclists

    Dear Mr. Liang, Ms. Sim, et al.,

    There has been some commotion after several cyclists were killed in road accidents, and after meeting with another reckless cyclists yesterday I feel I need to write to an authority about this before more people get hurt.

    I am not sure which ministry (LTA? SPF?) to send this to, hence I am writing to you.

    I recall that many years back there was an old man/lady being run over by a bicycle on pavement. Newspapers reported the incident and mentioned that bicycles are not allowed on pavements.

    Over the years it has become common knowledge that bicycles are not allowed on pavements and people have started to cycle on the roads. I am starting to see more and more people take up cycling, but these cyclists are becoming more of a nuisance and road hog, posing not only inconvenience but danger to both themselves and road users.

    I am a driver and cyclist myself and I usually cycle on pavements because I feel it is safer. I will give way to pedestrians when I meet them. Moreover my wife is not a very proficient cyclist, and I think that cycling on the road would be extremely dangerous.

    I have heard from friends that they get fined $50 for cycling on pavements, which I think is ridiculous if they weren’t cycling recklessly. Enforcement should be against any reckless cyclist, be it on the road or pavement.

    I’ve seen countless number of cyclists flout traffic rules, and here is one such incident causing an accident:
    http://singaporeseen.stomp.com.sg/stomp/sgseen/this_urban_jungle/1279106/reckless_cyclist_runs_red_light.html

    Another public video of a cyclist switching lanes recklessly at Jurong East and getting hit by a car (skip the first few seconds of the video):

    Along Woodlands Road all the way to Bukit Timah which I travel daily, the road is already very bumpy, winding and narrow due to the Downtown Line MRT construction:

    • Vehicles will need to keep an entire lane distance just to avoid the cyclists around the bends.
    • During peak hour this causes traffic jams and are a nuisance as bicycles are slow moving vehicles (20-30kph max).
    • These cyclists tend not to stop at traffic lights.

    Also, buses are very wide and use an entire lanes width. Since cyclists keep left and the left lanes are now mostly bus lanes, buses have to make bigger evasive maneuvers to avoid cyclists.

    I would like to suggest that we allow cyclists to cycle on pavements with the exception of electric bicycles which are much heavier and can go very fast (a lot of illegal ones are around nowadays).

    The rationale for my suggestion is:

    1. The probability of a pedestrian getting seriously injured being run over by a bicycle is less than having any form of motor vehicle hit a cyclist.
    2. There is no legislative requirement for cyclists to know traffic rules before they cycle on the road (e.g. basic theory test), and hence difficult to enforce.
    3. There is no legislative requirement for cyclists to be identified (e.g. number plate) and penalized for errant cycling, and hence difficult to enforce.
    4. We should not discourage people from cycling on pavements around the neighborhood. It is a cheap, green and healthy activity and can be a good family activity.
    5. I am aware that there are PCNs but the routes that PCNs take are sometimes not convenient if one uses bicycles as a mode of transport, e.g. to the market.

    Sincerely,
    Justin Lee

  • Cyclists: Road or Pavement?

    After some recent news about cyclists being run over by cars, people started saying things like cars pay for road tax, COE, ERP and hence cyclists need to stay off the road. Cyclists then start saying that their bikes don’t wear off the road. WTF?!

    See this forum discussion.

    I think some people are just damn narrow minded. It’s not about road tax, ERP or COE. It’s about your own safety when cycling.

    Law says you can ride on the road. It does not say you *must* ride on the road if you feel it’s not safe. There are park connectors. Hell screw it, even if there’s no park connectors I will *still* choose to ride on the pavement.

    Same goes for nobody says you *can* walk on the road, but some people still choose to walk on the road.

    And some cocks still choose to cycle 2 abreast on a busy or narrow road. I know the law says you *can*, doesn’t mean you *should*. This shows how selfish people can get. Bicycles are slow moving vehicles, and if you want to talk about rules of the road, then bikes should jolly well KEEP LEFT.

    I am for cycling on pavements, illegal or not.. my safety is my top priority. If the roads are too busy to cycle on, I’ll get on the pavement. On pavements bicycles should give way to human pedestrians, that’s about all we need to do for a peaceful society. I don’t know which civil service idiot said we can’t cycle on pavements. They should shoot themselves. The number of fatalities of cyclists vs. cars is certainly higher than old aunties vs. bicycles.

    Why not on the road? Because our roads are getting too crowded with bus lane and all. It poses even more danger to a cyclist AND other road users. The bicycle is slow and fragile. Riding alongside a road with bus or lorry going at twice its speed is so damn dangerous. People have to swerve to get away from crazy ass cyclists swinging left to right trying to pedal hard to keep up with road traffic speeds.

    Secondly there are lots of traffic rules to abide to when using the roads. A lot of cyclist do not follow these rules. They cycle on the road, then turn onto pedestrian crossings when they meet a red light, or simply beat the light, or turn into filter lanes, or cycle across zebra crossings. Just a few examples of the many many crazy cyclists I’ve seen.

    There’s no control over bicycles on the road. There’s no license plates to identify a person, there’s no (legislative) need to know road traffic rules to ride on the road, there’s no speed limit, no traffic camera — nothing, basically, to enforce that bicycles must adhere to traffic rules.

    And if you start telling me because you have a road bike hence you need to cycle on the road, then I can tell you I have a Ferrari and I should race on the roads too.

    It’s not always about the money. Your life is worth more than that.

  • Saving is a virtue, investing is a method

    I thought this would be a very good blog entry so I decided to write it.

    I was out with my junior from Ngee Ann Polytechnic. He wanted to get himself a nice Cello before he serves NS so we went Cello shopping. After viewing some nice instruments we sat down at TCC and I had a chat with him.

    My first advice to him was not to spend his life savings on a Cello. He assured me that that was not all the money he had and he had intended to use some of his savings to invest in blue chips. My first reaction was 😮 (not bad for a 19yr old!)

    I asked him, what kind of yield are you expecting from, say, $5,000.

    “5-7%”, he said.

    “That’s pretty much nothing”, I said.

    It works out to $250-$350 per year or about $20-30 per month if the yields meet his expectations. I told him that he’s still young and while his earning power is zero at the moment his expenditures are at an all time high. I sold him a new concept that at this point in life he should first learn to reduce his expenditure because that gives a better “yield” in relative dollars versus investing his life savings of several thousand dollars, not to mention the risks of investments.

    Afterall most people spend a larger portion of their income than save and it is generally easier to save 10% more than to earn an additional 10% from the savings.

    N.B. Saving does not mean scrimping, i.e. being a cheapskate to an extent that it impacts the wellbeing of yourself and people around you.

    One way to go about doing this is to leverage credit cards with cash rebates. But the bill must be paid in full at the end of each month, i.e. do not overspend. For example I have a UOB One card that gives me approx 3% cash-back on my expenses. If I spend on average $800 a month that works out to about $20+ per month, which is about the same amount that he would have gotten if his investments of $5,000 yielded 5%-7%.

    This is just one example, and probably not the best. There are many, many of these cards out there. I heard Standard Chartered even gives you $100 for a new sign up!

    If you are a student and not eligible for a card, just get an adult to sign up for you or be your guarantor. It is actually a good way to build a positive credit rating and to learn to manage your finances.

    Of course some apply for all the wrong reason, e.g. to get discounts eating out at fancy restaurants or simply to show off. It’s not that discounts are bad but when you keep eating out for the sake of that 15% discount, you are doing it for the wrong reasons. A plate of $3 chicken rice versus 15% off a $30 buffet is not savings.

    Without self control all these credit facilities can go out of hand and that’s exactly what the banks want — for you to default payment and pay the hefty 25% p.a. interest rate and $50 late payment fee, or to buy that Prada bag and miss one of your 12-month installments.

    Saving is a virtue and one should always start with that. Investment is one of the many methods to grow your money only when you already have enough money to go around.

  • Power Hungry

    Somebody once told me: Once you’ve driven a more powerful car, you won’t turn back. I guess thats really quite true.

    I’ve gone from my first car — a Nissan March (Micra in other countries) 1.0L to a new 1.5L Nissan and then to my current 2.0L BMW. I also used to drive my dad’s 2.4L Volvo when I first got my driving license. Power was never enough.

    The feeling of a vehicle with power on the tap is hard to describe. Many who have not driven a more powerful car may not understand and relate power with the need for speed. Of course I’m not talking about a Ferrari or a Bugatti but a normal road vehicle with sufficient power pulls you away safely in situations when you need it. In general, my personal figure is at least 100hp/tonne or more.

    I was in Melbourne a few years earlier where I rented a Holden SV6 3.6L V6 to drive up the Great Ocean Road. There were four of us and a boot full of luggages easily adding up to about 400 kilos but the car was still simply amazing to drive. It goes around the mountain roads effortlessly and merges with freeway traffic with ease.

    I specifically remember an exit from a farm road to the main freeway where I had to make a right turn (RHD in AU — which means I had to go across one direction of traffic before merging with the other). There was no way I could have waited for the right time to get on the freeway if I had been driving a 1.6L Toyota as there was simply too much traffic going at 100kph on the freeway. I waited for several minutes and found an opportunity where there was a gap in the traffic caused by a slow moving truck. I simply got on the gas and the car went right off and made the turn to merge with the traffic.

    I’ve had the opportunity to drive serveral new cars recently, namely the Audi A4 1.8T, VW Scirocco 1.4T, VW Polo 1.2T, Mini Cooper S 1.6T and the BMW 320i (F30) 2.0T. These are all amazing cars with turbocharged engines and they have loads of torque almost immediately off idle and are such a joy to drive even in our city traffic. In my opinion, there’s no reason not to consider these modern TC engines over the NA ones except for long-term reliability.

    Given the power improvements AND fuel economy, these turbo engines will be the future until a more efficient energy source after fossil fuel is found. At this point we have squeezed almost every bit of energy from gasoline and diesel. Hybrid or pure EV cars aren’t very practical yet IMHO. The need to wait a considerable amount of time to charge a battery makes it pointless. Some may argue: that’s nature and nature takes time to regenate (just like land for growing crops), but I am not at all convinced that electrical power generation is efficient given that most parts of the world still rely on some form of fossil fuel for electrical energy and the carbon footprint of setting up the entire electrical distribution infrastructure isn’t likely “CO2 friendly” either.

    Speaking of long-term reliability, modern NA engines are made of lightweight aluminium or magnesium alloys and they tend to give way under stress and heat. Weight plays a critical part in fuel economy since basic physics defines Force = Mass x Acceleration. There’s only so much force a gallon of fuel can provide and apart from reducing any frictional losses, the next step is to reduce the weight (mass) of a car. The engine is sometimes the heaviest thing in a car after the passengers (LOL) so auto manufactuers do put considable effort into reducing weight.

    The good news is that some of these modern TC engine blocks (especially VW/Audi) are still made from traditional cast iron and that might help them last longer. I am not entirely sure at this point but it seems that the BMW N20 2.0 TC engine found in 20i and 28i models of 2012 BMW vehicles (possibly also Mini Cooper S “Prince” engine) seem to be made of aluminium alloy. If that’s the case then that may be bad news given the history of the aluminium N46 engines developing gasket leaks past 60,000 kms.

    Nevertheless, most people don’t really keep their car past 5 years so auto manufacturers don’t emphasize on long term reliability like they used to in the good old 80s. Long term reliability is quite different from short term reliability. A simple example would be a transmission that could withstand loads of torque (short term) but rusts and leaks after some time (long term).

    Sometimes I wonder if all the talk about green technology gets defeated by consumerism.

    That said, one of my dream car is an old 1987+ BMW E30 320i. If I had time and money, I would almost certainly buy one and have it nicely done up. Unfortunately the car would be frowned upon by my government and I will be slapped with a 50% increase in annual road tax. Given the current COE prices, looks like I may never get to buy one unless maybe… I move out!

  • Real World Technology

    I’m leaving for Sydney later tonight and will be flying on the Airbus A380. I know we’ve heard about wing cracks on the A380 and wifey was just getting a little paranoid that we’re going to fly in a potentially cracking aircraft tonight.

    So wife’s paranoia* got me reading up on the cracks.

    * I’ll have to convince her it’s safe to fly or she’ll squeeze my arms so hard on take-off that blood just stops flowing.

    Anyway just to quickly summarize, the cracks were small hair-line cracks in the feet of ribs in the wings. This was a result of using newer, lightweight materials to save weight and improve fuel economy.

    If you make an aircraft bigger, it gets heavier so you’ll need to make the wings bigger and the engine more powerful. It’s only natural that fuel economy takes a hit.

    The automotive industry works similarly – the easier way was to make things more aerodynamic and lighter so that fuel economy improves, but with newer safety standards this is starting to become a challenge. Making an engine do more work with less fuel was the difficult part.

    The aircraft turbofan is already very efficient (at cruising speeds) but automotive fuel-saving technologies still has some ways to go. Nevertheless, the automotive industry has seen some pretty awesome new technologies in the past decade, which explains why I am such a fan of them.

    But I’m not going to talk about cars today. This brings me to another point: What drives technology?

    Technology is an integral part of our evolution and my belief is that real world needs are the main drivers of good technology. Unfortunately for the folks who would like to believe everything new is good, I do not believe its true. Good technology is not just any new technology, but technology that works to solve a real world problem – hence my love for automotive technology. In fact, old technology can sometimes be better than new technology.

    I think that aviation and automotive industries are two of the major drivers of technology; if not for space flight and aviation, we wouldn’t have GPS, accelerometers and gyroscopes in the iPhone today.

    In the recent years the automotive industry has gained a lot of traction. We’ve seen new engine technologies that improve both power and fuel efficiency, reduced emissions and new gadgets that improve safety. These are technologies put to real-world tests in everyday use, and these technologies are what I believe where the real money should be.

    Not social networking. Not group buying. Not building some iPhone app.

    Of course, these are just my personal opinions.

    In today’s fast-paced environment we are distracted by the Internet. Our thoughts are becoming more and more shallow and short-sighted. Most new technologies are built around dreams and desires rather than real needs.

    I’m not downplaying the importance of dreams but I my worry is that many are headed towards building dream/desire and we’ll soon be starved of real talents to serve our needs – and I think it’s already happening right now in our society.

    If you’re thinking of building the next big thing, give a few minutes to think about what I just wrote here.

  • MP4 videos on my bedroom TV!

    Just found out that the (not so) new 32″ Panasonic LCD TV (Japanese technology!) in our bedroom plays MP4 videos from a USB flash drive flawlessly! I wasn’t able to play AVI videos with all sorts of weird video codecs in them – usually DivX.

    I find the new LED TVs too bright and contrasty. Colors didn’t appear natural and I got this “old technology” LCD TV for $399 a few months back. It’s awesome and in fact very ideal for bedroom use as the lights in a bedroom are usually dimmer. Please grab them before Apple starts making TVs with iTunes built in that costs $1,488 or something like that.
