Private cars dont work period. its too inefficientYou never talk about the disadvantages of public transportation. If I did live in a big city, and I've driven in every major city in the U.S., except San Francisco, including at rush hour for many of them, I'd still pick driving a car over taking a bus or subway, which I've also done, as long as I could afford a car. I did without a car in Seattle and could take their bus system anywhere in the county. You just have to have patience and give yourself plenty of time. But I'd rather take a car there and even with heavy traffic go from point to point a lot faster. No waiting in the cold rain for the next bus. No walking blocks in the rain to get to your destination after getting off the bus. No trying to figure out which bus to take after sitting on a bus for 40 minutes and you're in a crowded terminal with a lot of buses coming and going. You can make it work, but it takes time, patience, and putting up with weather. And it's a fantasy to think we have the money to build trains everywhere or even have the kind of bus system Seattle has. The topography of some cities, like Seattle, wouldn't make trains feasible anyways.
Best bet is to get the best public trsnsport system you can get. its not a lot of money to just cover bus stops, put in good seats
