Re: Some points
Buses can be cheaper, but there's a price for that, of course. In my car I can travel when I want, with whom I want and with my choice of temperature and music. I can change my plans at the last minute. I can also use it for long journeys where bus/train simply isn't fast or convenient enough.
Of course I'll take the train when it is more convenient, it's all down to personal choice. I certainly don't consider not having a car as weird, many of my family members don't drive, but personally I couldn't imagine not having a car.
