Above ground parking puts a limit on density. And it causes a huge amount of traffic. On the road in front of my old office, 90% of traffic were cars circling in an attempt to find a parking lot (there were rarely free spots). And there were regularly cars honking at each other when someone took too long to get into a space. Obviously cars are environmentally a disaster, but people like them too much to give them up altogether. But if you drive a car, the least you can do is park it somewhere where it isn't taking away public space. (Parking cars are also in the way of other cars that try to get somewhere)
