Nature's had a 10 million year head start and I haven't seen any species being born with wheels.
4 billion, and a wheel would be almost impossible to evolve because it requires free motion independant of it's location and therefore couldn't be connected with any strand-based organs like viens, nerves, and other connections... a wheel simply couldn't evolve unless that limitation were worked around.
Driving down the highway in a car, if your engine fails, you pull over.
If your engine fails on one of these, you likely kill you and your family.
People used to say that about air planes.
The thing is... your car has 1 engine, if it fails you car stops. The flying car has like 8, and can fly on 2-4 of them... it is very unlikely that 4 engines will crap out at the same time... you would obviously want to stop flying if even 1 died.
cars are far more deadly than planes, mainly because average people don't fly the plane, but these flying cars will have to damn near fly themselves to be legal. They fly along computer controled GPS flying highways and know where all the other flying cars near them are at all times and will avoid them. They will be able to sense when things aren't right and won't take off if the condition of the craft is too poor to fly.
