That's the thing--personal aerial vehicles eliminate urban sprawl because destinations can be reached vertically with landing docks on a building's roof or side. It's easier to add a new layer of aerial streets than fix bad city planning, which LA has been trying to fruitlessly do for years.

This would also free up more roads for trucks hauling container shipments. It's frustrating and dangerous to have to constantly change lanes because some tractor trailer cut in front you on the road.
