Hover cars exist but no-one uses them. I think that when cars are computer controlled such that you can get in and it brings you where you want to go without hitting any car then we can start lifting them off the ground. The biggest problems with flying in a hover car is the risk of crashing with another hover car – if we can avoid them then the risk is gone.

I think it might take a while, not from the technology point of view but from the logistics. The infrastructure of every country is set up for road based vehicles, the laws and licences are also set up for this. All of this would have to be adapted, so it is possible, but it would have to be interesting financially for governments to push for it.

Google and others are looking at autonomous cars, which drive themselves. Most accidents are caused by driver error, so it would be pretty good if we could reduce accidents. Then after that we can think about moving on to hover cars. At the moment cars move in a 2-dimensional space. If that becomes 3-D, then it would become so much more difficult to manage, but I guess hover cars will be used in specialised situations in the future and who knows maybe your grandchildren woill be using them!

Like the others have said, the biggest issue is the added difficulty of adding a new dimension to the equation. Unless we are talking about hover cars that are only slightly off the ground to avoid friction and still effectively drive in a 2D space. I would say the technology for that would be able to be made now, but the increased cost and technical difficults probably far outweighs the benefit.
