I grew up with cars. That's it. There was no public transportation in Covington, and even now only has a couple of lines running through it. So, I grew up yearning to drive, then learning to drive, in order to escape. Cars represent freedom to me, and to many Americans. The feeling of not being beholden to anyone else is freeing.
I started riding the bus out of necessity when I was accepted to Cornish in downtown Seattle where there is an infamous lack of easy or affordable parking. And I realized then that I liked it most of the time. Not having to deal with idiot drivers, not having to pay attention to the road at all, it's nice. But there are terrible things about public transportation too - primarily other humans and their bad behavior. Smelly people, loud talkers, rude young folks who refuse to move their stuff, etc.
I think I will probably always prefer to drive if I can. It's a deeply-held love. But luckily for the planet, driving is only getting more and more expensive and frustrating. :)
