> * when in full-auto on a single lane road, when there's an exit on the right the Tesla 3 almost always slightly swerve towards the exit before coming back in its lane. None of the Megane, the EQE or the BMW i4 do that. A minor nuisance. Unless you happen to be at the ready attentively double-checking whatever the assistance is doing - then it must be infuriatingly annoying! Guess what you're supposed to be doing, all the time...

That's the point of assistance, it shouldn't need double checking by a human every time. It should just work.

  Unfortunately, Autopilot currently exists in the liminal space where it should just work... Unless it doesn't, in which case it's allowed to kick out with no margin of notice time and the driver is immediately responsible for what happens next. It's entirely possible that is an unsafe-at-any-speed configuration.

    It's sketchy at best. Our newest car does emergency braking and that's it. And it's good at it, only engaging when there is a situation it feels (and is correct) about me not braking in time or hard enough. I shouldn't have to worry about it failing.

  That’s the point of a Level 4 driver assistance system. Tesla’s Autopilot is 2 while Mercedes’ Drive Pilot is 3 in limited areas. Waymo is an example of a Level 4 system, albeit very limited in geographic area.

Someone tried to sell me a Tesla, and had me take it out on the highway to try Autopilot. The salesperson had the misfortune of suggesting I engage right when there was an exit coming up on the right. It wasn't a great first user experience to have the car immediately drift right towards the guardrail crusher.

Any car behaving differently to a human driver is outright dangerous. For example, motorcyclists depend on inferring behaviour more than the average driver. Someone swerving towards an exit is far more reliable an indicator of them taking it than a signal - many drivers don't bother using them. Many bikers I know avoid Teslas like the plague, as they're deeply difficult to read at best, and lethal at worst.

  Yowsa! Thanks for pointing this new hazard out! As someone who spends a fair amount of time on a bike in the city, I too depend on reading the body language of cars/drivers. You've given me something new and disturbing to think about...

  > Any car behaving differently to a human driver is outright dangerous. Any traffic participant (of any type) behaving sufficiently differently than the fat part of the bell curve for the situation (traffic, weather, location, vehicle type, time of day, etc) they are in is dangerous because they violate the expectations of all other road participants have for them. Other road participants need to be able to make reliable enough and accurate enough predictions of future state for things to work properly. This holds regardless of human or computer.

    At least in the UK, this is why learner drivers have a clear sign on the back of the car ("L"), and people who have only just passed their test are encouraged to display a similar sign ("P").

  THIS! It is critical to be aware of the surrounding traffic, and recognizing the driving style — the wheel angle and the current balance/attitude of the cars — is critical to understanding what they'll do next. Just one example a while ago in traffic on a highway, I slowed a bit and moved to the other side of my lane, barely thinking about it. Seconds later the car on my left suddenly drifted into my lane, right where we would have been and only feet off my front bumper. My wife exclaimed "How did you know that was going to happen?!?", and I said I'd just noticed in the corner of my vision an odd wiggle in their front wheel, like the driver's attention or direction was off. Sussing out what a driver is doing with any intersection, regardless of their signals, is key. Are they actually setting up to turn or stop, or just going along ignorantly? So far, I haven't yet noticed anything big from Teslas, but although I've done a lot less driving since COVID, I still have noticed that their road positions and attitudes are, ummm unique. But really good to know about this fake-move towards the exit lane — very helpful — Thanks!

I 'd freak out for sure. How can you be cool with your car changing direction when it should not? And how can someone not pay attention? What will you do? Sleep? Read a book?

  It tries to murder you from time to time too. This is at least a consistent glitch. I took a long road trip in a 3 with FSD and had I not been paying attention it would have sent me into a median once, and off to the ditch a second time.
