We have had helicopters now for 80 years, mostly used for military, oil rigs, rescue and the odd rich bastard.
Just because there is a new way to power these machines does not mean there will be a revolution and they will somehow solve all our problems.
Authorities make it nearly impossible to fly drones on Sydney Harbour, CBD or anywhere there are lots of people around. Why would the have a complete change of mind when it comes to flying cars?
If these things are not allowed to fly on the harbour or CBD where the people are then it kind of defeats the whole point of having them,
Blue mountains, country towns OK but we already have regional airlines that do that.
Actually, I thought the riderless motorcycle was more useful than the flying car (and being riderless it would not even need an ashtray)
