They said there is a compressor to re-pressurize the tanks while driving. It made it sound like a power-up in a video game. You can't use it all the time, but if you wait for it to charge up, use it as many times as you want.

I think the bigger issue with be making it street legal. Kickflipping over traffic, and refusing visibility for everyone to 0 in the process, can't be good.

For closed courses, movies, etc it's really cool.

I don’t think it would be street legal, hence the invite only thing. More of a status symbol / car collector curiosity than an actual car
