Yes, a walkable city would be great. But we have what we have. A few miles South of where I live in Florida is Sun City Center, a retirement community. They use golf carts to get around. It works well for them, but a little beefier car might be better suited to their needs. It would allow them further range mobility than a golf cart, along with better accident protection.

A few other thoughts on the air car: With a pressure outlet you would be able to run air power tools and not need an electric outlet. You could run a generator with the air power in case you needed to. With free air conditioning as a bonus, the car will really work well in the South, like where I live in Florida. I like that idea. The car seems ready-made for DIY projects and garage inventors. We will see what the market thinks after it goes on sale. I hope it is a success. It would seem to have a niche market if it can get established before battery power is able to.
