I think it's more than that. The more cars are going the less pleasant it becomes for everyone, also cars themselves. But a large amount of people does what everyone else does and just rationalises/justifies it somehow when challenged. I see the same with children. When I was young nobody wanted to be dropped off by their parents, everyone wanted to bike. I see it with my kids somewhat (they are still a bit young to bike to school alone here) and some colleagues kids (who are older) and it is an argument to bike to school. Interestingly this seems to be very school dependent some schools have almost all kids biking while others have none. It is almost like a phase transition.
