Passenger vehicle L4 while towing a trailer
That's not even a complete sentence. Are you asking if L4 is possible while towing a trailer? What are you trying to say?

Passenger vehicle L4 while towing a trailer
Passenger vehicles Cars and Pickups towing trailers operating at level 4 autonomy. Right now GM claims level 2 hands free driving. They also state supercruise will also work while towing a trailer. So hands free while towing.
I'm heading to SF next week, and plan on taking a few waymo rides while there.FSD beta testers ride in a driverless Waymo and are very impressed.

Video is from September 2021. They didn't have FSD Beta at the time, so the verbal comments aren't useful for comparison. They put some general written comments at 11:30 which do reflect their later experience with FSD Beta.FSD beta testers ride in a driverless Waymo and are very impressed.

Waymo dialed up the confidence since the JJRicks videos, and probably has gone further since. There's an unprotected left at 3:00 where it looks a tiny bit twitchy while waiting but does not proceed until clear. It starts the turn while the last oncoming vehicle is still in the intersection, more aggressive than I recall. It makes a left in front of an oncoming car at 5:20. It wasn't dangerous, but rattled the couple. I don't remember JJ's cars being nearly that aggressive.
It's possible that adding a level of temporal recursion to the neural networks for vision processing will get rid of some of the jerkiness as well. In a recurrent neural network, each processed video frame won't necessarily result in a new, independent prediction.I think those smooth turns without steering wheel jerking around is a "must" and elementary. I am an old school Control System Engineer and think that Tesla really need to hire a good Control System Expert to handle these underdamp/overdamp system conditions. It's not just software programming and AI.
“Cruise’s driverless cars experienced serious issues Tuesday night with as many as 20 of its vehicles standing motionless for about two hours at the corner of Gough and Fulton streets, according to an eyewitness. The incident was only resolved when the robo-cars were manually moved out of the way by Cruise staff.”
Agreed. I think attention monitoring is necessary but not sufficient.
E.g. With the current capability of Tesla FSD it’s absolutely essential you have your hands on the wheel at all times. Sudden steering movements can happen at any time and the delay if you have your hands off the wheel will likely lead to overcorrection or under correction in the event of sudden unexplained steering events (just happened to me this morning, sudden jerk towards adjacent left turn lane with a car in it; immediate disengagement).
I guess we’ll see how it pans out. With the limited domains right now probably SuperCruise is not an issue to be hands off. For UltraCruise not so sure. Depends on capability. If it can give some very short warning (borderline L3 but not L3) it might be perfectly safe.
I assume they have touch sensors if needed.
Yes. As I said I have no problem satisfying the nags. However, they are extremely annoying.But that being said, I’ve noticed, if you stare straight without turning your head significantly, the steering nags will relax down to 1.5-2 minutes gaps.

The early L2 systems from major manufacturers were jarring too (ping pong between lanes) and it was suggested it keeps people more alert. But now most systems have been improved to smooth things out, so while there may be some truth to it, I'm not sure it's a major factor. Using cameras to monitor the driver probably is a more reliable way to ensure they are paying attention. Smoothing things out probably is just lower priority at this point.Pretty sure Elon said in an interview recently that driving comfort is currently being deprioritized, and they are focused on zero disengagements in urban areas first. So I don't think the issue is a lack of control system expertise.
At the same time, I don't buy that smoother control can't be improved in parallel with proper decision-making. Which implies that Tesla might be keeping the system jarring to make sure people stay alert while testing.
Cruise PR says they used both in the statement linked above. Depending on what the bug was however, it might affect remote retrieval too and make it not possible. The anonymous Cruise employee said the issue was such that it required manual retrieval though. Not enough details to tell either way.Do these vehicles have remote operators that can prevent this sort thing from happening?
