People always end up petitioning for them to be cutdown because tree litter inevitably falls on cars. The best solution for cars is dense multistory parking.

In South Korea, you usually don't see parking lots the size of several football fields like in the U.S., even around venues that generally attract a lot of cars, even in suburban areas. Instead, there are several stories of parking lots under every large building. Above-ground space is simply too valuable to waste on parking.

Unfortunately, you can't install solar panels underground.
