Michael Reeves I think had a skit that was about half way there last year. (Being facetious). He rigged together 4 electric scooters and a remote steering wheel because he was bored I'm fairly sure.

Has the hardware evolved substantially? He's made big promises that seem to make it hard to add major upgrades. They aren't running something like an H-100 in a Tesla. It probably doesn't even compete with a 5090. At least segmentation models are tiny, but trusting the small ones is not a great idea...
