The last time I looked into it (which was admittedly a few months ago) Comma.ai was by their own admission a Level 2 system, and a somewhat sketchy one at that.

The last time I looked into it (which was admittedly a few months ago) Comma.ai was by their own admission a Level 2 system, and a somewhat sketchy one at that. While it's obviously really cool, it's a long way off from Level 5. LIDAR currently being very expensive (and a bit bulky) is obviously the reason Tesla hasn't put LIDAR in their cars. I don't really fault them for that, I fault them for their deceptive advertising. The LIDAR industry has not yet progressed to the point where it makes sense to bring a car to market with hardware ready for Level 5 automation, so Tesla should stop claiming they've done so. Assuming the current Level 5 automation hype doesn't fizzle then smoulder for decades like the AI craze of the 60s, then it's success will coincide with rapid advances in size and price of LIDAR.
