I wonder if ubiquity doesn’t effect the lidar performance? Wouldn’t the systems see each other’s laser projections if there are multiple cars close to each other? Also is LIDAR immune to other issues like bright 3rd party sources? At least on iPhone I’m having faceid performance degradation. Also, I suspect other issues like thin or transparent objects net being detected.

With vision you rely on external source or flood light. Its also how our civilization is designed to function in first place.

Anyway, the whole self driving obsession is ridiculous because being driven around in a bad traffic isn’t that much better than driving in bad traffic. It’s cool but can’t beat a the public infrastructure since you can’t make the car dissipated when not in use.

IMHO, connectivity to simulate public transport can be the real sweet spot, regardless of sensor types. Coordinated cars can solve traffic and pretend to be trains.

I'd assume not since Waymo uses lidar and has entire depots of them driving around in close proximity when not in use.

I'm not a self-driving believer (never had the opportunity to try it, actually), but I'd say bad traffic would be the number one case where I'd want it. I don't mind highway driving, or city driving if traffic is good, but stop and go traffic is torture to me. I'd much rather just be on my phone, or read a book or something.

Agreed that public transportation is usually the best option in either case, though.

LIDAR systems use timing, phase locking, and software filtering to identify and eliminate interference from other units. There is still risk of interference, resulting in reduced range, noise, etc.
