How do bats navigate the 3d space, considering they flight at night without any sort of good vision? bats never collide with each other, even in large quantities. They have a sort of radar system using sound; wikipedia calls it a 'biosonar'. Flying cars should have the same system to avoid collisions, and the cars should not be allowed to be totally manually driven (a limited manuevrability should be available that has lower priority than auto control).
But I guess it would take more than 13 years of research to put such a high tech marvel to market...
