I like the freedom a private car gives me. I can go anywhere at anytime. I have nothing against public transportation and want it to be good. But you can't go everywhere at anytime. Here I'm including the country side and smaller towns.
This is a solved problem in countries with modern public transportation. In Japan for example you can go across the entire country without needing a single car, and indeed it's both cheaper and more available than doing so while driving. If you need to go somewhere really far out of the way that is not reachable by foot or bicycle, then you can rent a car.
All of this results in a system that is far cheaper for you and far more open for the average individual.
