Funny you should mention GM, they had: https://en.wikipedia.org/wiki/MagneRide

Bosch had electromagnetic car suspensions figured out 20 years ago: https://www.youtube.com/watch?v=3KPYIaks1UY

The car industry is a perfect example of "worst is better".

The point about the cheap golf-kart car from China is about how little in terms of material costs actually goes into it. It is $5,000 shipped. In actuality it is about $2000 in parts.

The skateboard platform I linked to is already developed, they are supposedly going public this year, not just a concept.

If they can get them to pack flat (or flat-ish), they can ship quite a lot of them around the world for peanuts. Add whatever cab, wheels and branding you want to finish it off.

All of this stuff is about to become a commodity. The most, and basically only, expensive part is the battery.
