it would be scary yes - until there is the technology to make flying/shuttle cars safe. There would be no need for Air Traffic controllers if each car was able to negotiate the airspace by 'interlinking' with other vehicles and buildings around it.

yoo have great faith in technology! none of it is foolproof .......nevermind what happens when the system breaks down!

I get a bit scared when I hear those little planes doing their 'stunts' in the airspace near us. They cut their engines and I think there is a chance they can land on a house or two. Obviously there is a risk of it happening - it has happened in Salford. The night before it happened I actually had a nightmare about an aircraft crashing into 2 houses!

maybe that's all the air traffic control that's needed..... ?
