re - Car, I think there are 4 categories:
- those who need one (as I said, there are parts of HK that are not that well covered in terms of public transport and those with larger families or elderlies to carry around) and have the means to buy one.
- those who could need one but do not have the means to buy one.
- those who do not need one and do not own one
- those who do not need one but buy one for the occasional ride or status (have a few friends having the usual Porsche for the weekend rides)
So simply stating a car is not needed in HK is simply wrong. There are always special cases where a car will be more convenient/faster.
That does not mean HK transport system isn't great, it is, just that certain situation require sometimes a car.
