Highways will support not only cars but bus rapid transit.

In 2010, Selangor saw 25% increase in labour force. Very explosive population growth due to inter state migration. Thats equivalent to  10% of sabah sarawak population moving to selangor

i think the contributor towards car usage is cheap gas, despite our expensive car price, our petrol is 7th cheapest in the world.

it is a catch 22. take bus transportation for example, the cause of inconsistent schedule is because buses get stuck in traffic jams. even if Rapid adds more buses, the problem only gets compounded as more buses contribute to the jam. due to inconsistent schedule, less people take public transport, especially since we have cheap petrol. and that means rapid is less likely to add new routes cause demand isn't there.

i think luxury is a significant part why people drive. in developed countries, white collar workers waking at 5AM is normal because they need to take the early bus. in malaysia some ppl do enjoy luxury of waking up after 7-8 and still making it to their office cause they can use their cars.

in any case, I don't think highways contribute to the problem when it can be used for BRT (e.g. bus only lane).
