It doesn't because cars stick to the road. The difference is a little hand wavy and path dependent on history, but pilots are required to file flight plans; nobody requires a drive plan. (Of course, every car has a license plate and if somebody were to establish an infrastructure for tracking all of those plates and correlating it to motion of vehicles... I'm actually not against that. I'm of the personal opinion that we are far too deferential to drivers and do not demand nearly enough responsibility from them, and the fatality rates on roads are demonstrative of this).
