I love my Model 3, but everything you said is spot on. Autopilot is a great driver assist, but it is nowhere near autonomous driving. I was using it on the highway and was passing a truck on the left. The road veered left and the truck did as well, keeping in its lane the entire time. The car interpreted this as the truck merging over into my lane and slammed the brakes. Fortunately, I was able to figure out what went wrong and quickly accelerated myself so as to not become a hazard to the cars behind me.
Using Autopilot as anything more than a nice dynamic cruise control setting is putting your life, and other lives, in danger.
Holy shit. My car doing that once and I'd be a nervous wreck just thinking about using it again.
I have had the adaptive cruise control brake on multiple Hondas and Subarus in similar situations. Not like slamming on the brakes, but firm enough to confuse the hell out of me.
Every time it was confusing and now I just don't use it if the road is anything but open and clear.
Honda’s sensing system will read shadows from bridges as obstructions in the road that it needs to brake for. It’s easy enough to accelerate out of the slowdown, but I was surprised to find that there is apparently no radar check to see if the obstruction is real.
My current vehicle doesn’t have that issue, so either the programming has been improved or the vendor for the sensing systems is a different one (different vehicle make, so it’s entirely possible).
