While that may be true if you speak for yourself like a single person. But what if you are a couple, or a family?

For a long time I did not want a car but when children came, we have bought it and it help our mobility a lot, if you have full car, it is also cheaper travel than paying tickets for everybody. For a travel inside a city I still use public transport wherever I can as it is the fastest and most green way to get around.
