Walking or cycling is fine in many other countries, but maybe not in Thailand where the hot and humid climate is a deterrent for most. Cycling seems more suitable as a hobby or another form of exercise.
The best alternative so far still seems to be mass-transit revolving around an electric train system covering all parts of Bangkok. We still have only a few lines running.
If the government really wants motorists to leave their cars at home – and collect more road tax like how the UK has implemented a congestion charge in London – there must be a comprehensive coverage of mass-transit lines in place first.
Only until then can Bangkok start talking about car-free days. A genuine alternative for motorists all over the capital must exist first, not just on Sukhumvit or Phaholyothin roads.
