That argument doesn't make sense because human vision isn't that great either. When it's dark or raining or snowing or foggy our vision is pretty shit.
I'm not saying LIDAR is better but rather point out that actually you want different types of sensors to accurately assess the traffic, because just one type of sensor isn't likely to cut it. If you look at other manufacturers they're not using only LIDAR or only camera. Some use LIDAR + camera, some user RADAR + camera, some user LIDAR, RADAR and camera. And I'm pretty sure that as manufacturers will aim for higher SAE levels they will add even more sensor into their cars. It's only Tesla who thinks they can somehow do more with less.
People here have no idea what they are talking about, or how absurdly difficult it is to actually deploy lidar to a consumer vehicle. There's a reason why Tesla is shipping more advanced driver assist tech than anyone else, and it's because they went against the venture capitalist Lidar obsession which is holding everyone back. There's a reason why there are basically zero cars shipping with lidar today.
You don't need mm depth maps to do self driving. Not that you get that from lidar on rough roads anyway.
There are some test cars with lidar. It has the spinny thing on top and looks pretty interesting. I believe those cars are pretty successful. I don't think they're being mass produced though, because the costs might be a little prohibitive.
The most advanced that's not even on autonomous level 3. It's funny that Mercedes is the first to get level 3 approval in California and they don't even boasting that as much.
That aside, a secondary sensor that help verifying if the vision get it right would be nice. It could be just a radar or whatever. Imagine if the vision fail to recognize a boy in a Halloween costume as a person, at least the secondary sensor will the car to stop due to contradict perception.
I might be misremembering but I think Teslas are actually more capable, they're just deliberately stating they're SAE level 2 so they could skirt the law and play loose and dangerous with their public beta test.
I haven't researched this enough, but Tesla says that they are level 3, but never bother to get the actual approval is like how I kept saying that I'm smart, but too lazy back in my school years.
Put your money where your mouth is. Life are at stake here.
I think it's undeniable the combination of camera and lidar will be the best solution. I just hope this can be coss effective. Maybe over time we can be able to adapt and improve the technology and make it more economical so that it is safer for our roads.
