Most of the “driver aids” available today have the competency of a drunk or highly inexperienced driver. Just maintaining lane is a problem for all the systems I have had the opportunity to try. They are easily flummoxed by worn or moved lane lines (like you would see in a construction area). I view it as a definite upgrade over traditional cruise control, but it’s so far away from self driving it’s laughable to even think about.

i recently rented a late model rav4 and described the experience of radar cruise (on an admittedly challenging road) to be "like having a drunk lead-footed teenager at the wheel." lots of overaggressive acceleration and deceleration, with all too frequent state changes. personally i'd rather just have regular cruise and something that will drive the car competently at low speeds in heavy congestion.

  I currently drive a 2021 Rav4 Prime and it's not like that at all. The adaptive cruise control is smooth and never makes mistakes. Lane assistance is helpful but not as close to flawless, mostly due to poorly marked lanes.

    was it on flat roads or more challenging terrain? it was apparent that it was a very simple system that did not attempt to do any estimation beyond what was immediately visible to the sensors. so if there was a change in the pitch of the road, it would immediately react as the sensors became occluded and then regained their field of view. maybe in situations that challenging, it should complain and force manual control. rav4 primes look like awesome vehicles by the way... if i were going to get a late model green vehicle, it would definitely be on my shortlist.

      > so if there was a change in the pitch of the road, it would immediately react as the sensors became occluded and then regained their field of view I've used it on miles of interstate in the mountains, but that's never a problem because interstates don't change pitch that rapidly (by design). You must be using it on a very different roads than I do. I only use it on large, US interstates.

    Haven’t checked, but it’s possible that the RAV4 and RAV4 Prime use different hardware and software.

My 2018 Honda Civic variable speed control was excellent. Its lane assistance was crap. My 2022 Honda Civic variable speed control is even better, and the lane assistance is outstanding. The thing basically drives itself in 90% of the conditions I find myself in. The experience has convinced me that iteration is going to get us to where we want to be given moderate timelines even if Tesla goes away, which, I wish they would because, like everything Musk is involved in, it's a dramatic shit show.
