In some cultures, "overuse" of personal transport (if we want to put it this way) is a vicious circle of context and individual; it's not simply a fault of the latter.

Public transport underdeveloped -> more people use personal transport -> public transport develops even less, city develops around personal transport -> vicious circle.

Of course the individual it's a purely not victim, but in certain contexts, using the car is a necessity. In such cases, a strong collective effort should be made to reverse the situation.
