George Hotz has done some interesting work, but Comma is far too indie/hacker. It's not at a scale where it can be 100% autonomous.

I think a fully autonomous car has to be designed around LiDAR and autonomy from the ground up. That's a hugely capital intensive task that integrates a lot of domains and data. And so much money and talent.

This is more in the ballpark of Google Waymo, Amazon Zoox, Tesla/xAI, Rivian, Apple, etc.

And as the other folks have mentioned, this becomes a really good prospect if one company can manage the autonomy, insurance, maintenance, updates, etc. A fully vertically integrated subscription offering on top of specially purposed hardware you either lease or purchase.
