Why not both de-emphasize cities and make them better places to live?

There's already permeable blacktop, but I'm not sure there's much to be
gained by that except possibly replenishing the water table.

I'd rather see ground-level transport go away in favor of subways and/or
elevated rail. If streets could be replaced with real greenspace for, e.g.,
vegetable gardening that would be a big win.

We dont' even have roofs covered with solar yet.

There shouldn't be ground-level traffic other than human-powered. IMO.

Surely wireless is better for that.

Sorry, solar grass I can buy, but solar grass that can withstand vehicle
traffic and move vehicles out of the way is asking a bit much.

Or perhaps have real trees that purify air and use motion-activated LED

I wouldn't recommend it. It's not an efficient use of your time and money.
