OMG, I'd pay $10K for this. I find I'm constantly fighting the so-called "TACC", because it's neither traffic- nor speed-limit aware. Some of the stupidity I've come to hate:Have the option to turn off Adaptive Cruise Control and just use regular CC. Adaptive Cruise Control has a tendency to slow down very abruptly when you don't want it to and speed up when it shouldn't.
I'll set the cruise just above the posted speed as I come into a new speed zone, and it'll immediately drop the setting back to the posted limit. Why? I literally just set a speed, just do what I asked!
I'll come into a slower speed zone, but traffic hasn't yet slowed down, and TACC will set the lower limit immediately and start decelerating... why does TACC need to brake-check the traffic behind me? Just go with the flow FFS!
In construction zones, TACC constantly ignores the set speed (lower than posted speed) and tries to accelerate to either a) the posted temporary speed limit, or worse b) the full speed limit from the road (take from an internal database, or something?). Either way, it's suddenly jumping at the car in front of me or trying to blast through the construction zone. Why? I set a safe speed, just obey the speed setting!
I've come to hate TACC/AP/FSD over the past few weeks - it was bad before, but the FSD beta has made it terrible.
My worst fear about TACC/AP/FSD is Elon's comment that "all input is error" - it's totally backwards. Human input is a statement of intentions, and the system's job should be to follow the human's intent, except where it's obviously unsafe (e.g. accelerating into a storefront). If this is the driving philosophy behind Tesla, I suspect my M3 is going to get even more undrivable.
