Re: No wheel is one thing
"Works fine on combat aircraft, and large airliners, so I'm not sure where you got that idea."
So aircraft regularly fly within a few feet of each other going in opposite directions do they or are in situations where literally being a few inches out could cause a crash?
No, I think not. Even fighter aircraft have a whole sky to play, they're not surrounded by other 2 ton boxes of metal going at high speed. And formation display pilots have to train the same routines over and over again for years and have to know exactly where the other aircraft are at all times. Good luck trying that out with cars on the M25.
