Where we're going…we'll probably still need roads, actually. Even so, FLYING CAR FLYING CAR FLYING CAR!!!
Remember that person in front of you on the freeway the other day that had their turn signal on for like 7 miles? Yeah, someone wants to equip them with a pair of spinning blades and send them on their merry way, which may or may not involve traveling directly over your house. That's not going to be a problem for you, is it?
