Self-Driving Cars

I am rebuilding a 1967 Austin Mini (in my spare time)One of my reasons for getting it is that there are no green circuit boards in it. None.Recently I saw an architectural vision for putting bicycle lanes inside elevated tubes above the car lanes in cities. Now I'm thinking that these would need to be ventilated with clean air (or at least cleaner than at street level), and why not have that air pumped at 30mph (50kph) in the direction of the bike lanes, eliminating wind resistance and making it easy for cyclists to travel around cities at the same speeds as the cars. The air pumps could be powered by wind\solar systems (or augmented by them), and so using bikes would reduce vehicle congestion AND pollution.Then you use buses to take your bike between cities.That would be smart eh?Enjoy.
