Against flying cars
Having seen the idiots on the road and the petrol-heads who modify their cars to the point where they're actually dangerous to be on the road... and let's not forget the "joy riders" who wouldn't know their left from their right....
It's bad enough having them on the ROADS where they have few options in terms of carnage... do you REALLY want these people to have a capability of flying over your house?
And let's not forget that the top two reasons for plane crashes these days are 1) pilot error; and 2) maintenance f*-up by the airline company. Do you *really* trust the average teenager to maintain this vehicle properly?
No thanks... I'll forgo the pleasures of the flying car if it means I can sleep at night.
