Would lidar detect such debris?

It would depend on how dense the point cloud is, however at 100ft I'm guessing the resolution for something like waymo would be on the order of 10-20cm, which would suggest it wouldn't be able to detect it (at a minimum it wouldn't know its height, and thus it wouldn't know if it's a piece of paper or a steel box). My guess is it also wouldn't know until it's right on top of it

Where did you get 10-20 cm? That sounds wildly off. Commercial lidar would get you to ~3-5 cm at 100 feet easily and Waymo's is said to be better than the commercially available units.

Boring Company. Whatever happened to those tunnels?

They've only built out the system at the Las Vegas Convention Center, and every other project seems to have fallen through.

Tesla's cant even navigate the tunnels they made themselves without a driver, it's really impressive.

At 14:40 in the video they show the footage to a cop who's immediate reaction is

"To be honest with you. {talked over} you decide to change lane. How come you, did you think to change lanes or you just kinda froze up in that moment?"

He clearly thought they had plenty of time to react to it.

It doesn't have to do with the conditions. It has to do with whether or not it's on the highway or not. The car uses a different Stack for highway and off highway, the highway has been a step child for quite a long time now

That used to be true. Autopilot was for highways, FSD was for other roads. FSD can be enabled on both since v12 though and this video is specifically an attempt to use FSD on highways to go cross country.

Autopilot and FSD are completely different technologies. When v12 came out it only worked on city streets, and it used V11 for the highway.

Later, V12, which is the end-to-end neural network, worked on highways as well, but they use different stacks behind the scenes.

Is there any engineering culture left in the US? I feel like this is the case across the board.

Yes, there is. In every place that I've worked, including my current position, acknowledging when you're wrong or have failed at something increases trust in you and your professionalism. People who always have an excuse, try to shift blame, etc., are assumed to be lacking in competency (let alone ethics and trustworthiness).

The point is not to have an excuse or shift blame, but just talk over the issue "tired of talking about $thing", and shift the conversation.

Fuel tax is a big factor, but US has a lot of road. The US has 3x the amount of paved surface vs. Germany. European winters are also milder than the US. I'm not sure how many European roads would survive going from -10 to 140 like they do in the midwest

Actually, that's surprisingly little roads in the US. The population is significantly larger (more than 3x), so on a per person basis roads in Germany see much more use than in the US. And roads there are in a much better state than in the use despite the higher usage rate. So also as a consequence of this: If the US were to use the same per person $ amount to upkeep their roads, US roads would have WAY more money to…

Doh! I left out a key detail. The US has 3x the paved surface per person!

The debris is pretty close to the color of the road. Seems like a good case for radar/lidar ¯\_(ツ)_/¯

Yeah! Just add more sensors! We're only 992 more sensors away from full self-driving! It totally works that way! The debris? The very visible piece of debris? The piece of debris that a third party camera inside the car did in fact see? Adding 2 radars and 5 LIDARs would totally solve that! For fuck's sake, I am tired of this worn out argument. The bottleneck of self-driving isn't sensors. It was never sensors. The b…

Adding more sensors (such as LIDAR) can certainly make it easier for the "AI" (Computer Vision) to detect & identify the object.

Two more years guys, just give him two more years, a few more billion, a bit more political power and I promise he'll give you your fancy self driving toy. (Repeat from 2012 ad infinitum)

If it's not your money does it matter? I don't think it's fair to say he doesn't deliver anything e.g. he did cars, rockets, and now AI (the rate X are building out training capacity is genuinely astonishing) at the same time.

SpaceX and the Starship development is heavily funded by tax-payer money...

Also more VMT, which would tend to balance the excess roads, because more driving leads to more fuel tax revenue. USA has more than double the VMT per capita of Germany. If the fuel tax was appropriately set, then this factor would compensate for the greater sizes of the roads.

Kinda sorta.

It only operates a few hours a day, and the cars are not self-driving.

It's like a dedicated tunnel for Ubers.
