There has been a myriad of improvements in traditional petrol engines?

Yet our cars still can't fly, and still emit greenhouse gases...

[yreg]

Are you waiting for a petrol engine that doesn't emit gases? I don't understand your comment.

[wizofaus]

Why not? We've been promised carbon capture forever...

We do have flying cars.

[wizofaus]

Can you name a single person you know of with one?

[yreg]

I know a person who built one (actually more than one). Issue is that I don't think it's a good idea.

It's amazing what we do have. Just the computers alone are more than anyone could have ever imagined. But as for flying cars, they do exist, but we just don't need them.

Isn't this called a helicopter? Aside from the noise, etc. issues with them, what would be the difference between a flying car and a helicopter? The need for a pilot's license to fly one?

Price and ease of street parking come to mind!
