For several months now, when in bumper-to-bumper traffic, if my lane (usually the HOV lane, to the far left) is moving faster than the traffic in the lane to my right, my car, while on EAP, will suddenly lock onto one of the cars in the lane to the right and slow down as if it's actually in my lane. This only happens when both lanes are quite slow - say, 10 mph for mine and 5 mph for the other lane. If I'm doing 50 and the adjacent lane is doing 40, there are no such problems, thank goodness, but even at slow speeds, this is annoying and potentially dangerous, from a property damage standpoint, at least. I can override the behavior with some force on the accelerator, but of course that defeats the purpose of EAP, which used to be especially useful to me in this kind of traffic. Note that this is not the well-known behavior of a slight slowdown, accompanied by chevrons appearing in the adjacent lane on the screen. I think my car, in this situation, would actually stop if I allowed it to.
I can see that it's picking up the car it's slowing for, as that car turns black on the display (see attached photo). The cars seem to first change to black on the screen when their brake lights are illuminated, though once black they usually stay that way until I pass them after overriding the slowdown with my right foot. I'm guessing my car is, for some reason, thinking that they're stopping in front of me, though they're not exhibiting any drift into my lane, nor are their turn signals coming on.
My car has been on Tesla Vision for probably a year now, but this problem has developed much more recently, so I don't think it's solely because of Tesla Vision; while this never happened when I was still on radar, I all the same had probably a half-year or more of great driving on Tesla Vision before this issue appeared. I'm currently on version 2023.7.30, and have had this problem for the last two or three software versions.
I've tried recalibrating the cameras multiple times and cleaning the windshield really well, all to no avail. If I use FSD rather than EAP, the problem still occurs, though maybe it's slightly less bad; unfortunately, FSD simply doesn't work well enough for my highway commute so it would not be a viable option for me even if it solved this problem. (FSD often wants to jump into left-exits from the HOV lane when it should continue straight, it makes bad lane change and navigation decisions, and so on, but that's a story for another post.)
I have an appointment for Tesla to try to diagnose the problem, but things keep coming up in my schedule and I keep having to move the appointment, so I thought I'd at least ask here if anyone else has seen anything similar, and if so, if they or Tesla ever solved the issue.
Thanks, everyone!
