I watched that video around both timestamps and didn't see or hear any mention of LIDAR, only of video.
Exactly: they convert video into a world model representation suitable for 3D exploration and simulation without using LIDAR (except perhaps for scale calibration).

Why is this relevant at all? Having humans in the loop at some level is necessary for handling rare edge cases safely.
If that’s true the system isn’t finished. That’s what reasoning is for.
Seems interesting, but why is it broken. Waymo repeatedly directed multiple automated vehicles into the private alley off of 5th near Brannan in SF even after being told none of them have any business there ever, period. If they can sense the weather and stuff then maybe they could put out a virtual sign or fence that notes what appears to be a road is neither a through way nor open to the public? I'm really bullish…
I think you meant, "Attempt" to limit what people can do.
Driving in SF (for example) provides many opportunities to see "free will" exerted in the most extreme ways -- laws be damned.
What's going to happen to all the millions of drivers who will lose their job overnight? In a country with 100 million guns, are we really sure we've thought this through?

The purpose of lidar is to prove error correction when you need it most in terms of camera accuracy loss. Humans do this, just in the sense of depth perception with both eyes.
(Always worth noting, human depth perception is not just based on stereoscopic vision, but also with focal distance, which is why so many people get simulator sickness from stereoscopic 3d VR)
Also subtle head and eye movements, which is something a lot of people like to ignore when discussing camera-based autonomy. Your eyes are always moving around which changes the perspective and gives a much better view of depth as we observe parallax effects. If you need a better view in a given direction you can turn or move your head. Fixed cameras mounted to a car's windshield can't do either of those things, so you need many more of them at higher resolutions to even come close to the amount of data the human eye can gather.

Hesai has driven the cost into the $200 to 400 range now. That said I don't know what they cost for the ones needed for driving. Either way we've gone from thousands or tens of thousands into the hundreds dollar range now.
Looking at prices, I think you are wrong and automotive Lidar is still in the 4 to 5 figure range. HESAI might ship Lidar units that cheap, but automotive grade still seems quite expensive: https://www.cratustech.com/shop/lidar/
One interesting thing from this paper is how big of a LiDaR shadow there is around the waymo car which suggests they rely on cameras for anything close (maybe they have radar too?). Seems LiDaR is only useful for distant objects.

> Self driving cars will literally become a part of public transit I’ve been hearing people say that for almost 15 years now. I believe it when I see it.
I'm willing to wager that you might not actually believe it at that point either.

Yes, let's stop all progress and roll-back all automation to keep hypothetical angry people with guns happy.
Autonomous private cars is not the technological progress you think it is. We’ve had autonomous trains for decades, and while it provides us with a more efficient and cost effective public transit system, it didn’t open the doors for the next revolutionary technology. Self driving cars is a dead end technology, that will introduce a whole host of new problems which are already solved with public transit, better urban…
I would be happy to bet on some strict definition of your claim.

Nope. Humans are statistically fallible and their attention is too valuable to be obliged to a mundane task like executing navigation commands. Redesigning and rebuilding city transportation infrastructure isn't happening, look around. Also personal agency limits public transportation as a solution.
Unlike autonomous driving, public transit is a proven solution employed in thousands of cities around the world, on various scales, economies, etc. > Redesigning and rebuilding city transportation infrastructure isn't happening, look around. We have been redesigning and rebuilding city transportation infrastructure since we had cities. Where I live (Seattle) they are opening a new light rail bridge crossing just next…
66 years later we see California struggling terribly with implementation of a high-speed rail system -- where the placement/location of the infrastructure largely is targeted for areas far less dense than the Bay Area.
I don't think there is any single reason why this is so much more difficult now then it was in 1960 -- but clearly things have changed quite a lot in that time.
