Just FYI there are some spots on the 401 now where they are widening lanes from Milton to Mississauga that have messed up the car's interpretation of what road you're actually on. There's a weigh station that doesn't exist anymore that registers a 40km/hr speed limit for example. Autopilot will definitely react and TACC from my experience sometimes reacts and sometimes doesn't (maybe it also uses awareness of traffic speed of other cars around the vehicle...who knows).
There are certain exits around Montreal where I consistently see the TACC target speed drop suddenly even when I'm not taking the exit. Some of these changes in target speed are extremely short-lived, then the target subsequently changes back to my previous setting. I've reported these anomalies to Tesla with no response. It seems that the vehicle uses data from roadside signs but these are overlaid onto an existing speed limit database which contains some imperfections and discontinuities. I also surmise that some of these speed changes might be intended to prevent FSD from taking an exit too fast, although I really wish the car would let me be the driver because I'm in charge without FSD. As I understand it, these are not considered phantom braking events. That phenomenon is caused by another vehicle or overpass (or sometimes nothing at all) that Autopilot senses as a collision risk and it decelerates abruptly to avoid the perceived collision. My only experiences of this have been when passing a stopped truck that wasn't far enough onto the shoulder, and approaching an overpass on a downhill slope.Hello Everyone,
greets from Ontario.
regarding the phantom braking apperances, I have to join the subject. I have a 2022 M3LR, received last saturday 18. Dec. 2021.
Yesterday evening , I was driving the route London, ON to Toronto Airport and back on the 401 Highway. The complete drive was after sunset. The set speed in cruise control only (110 to 120 kmh) , without autosteering. I do not have FSD.
The phantom braking did appear really out of the blue cruising with 110kmh when getting close to off-ramps, being on the most right snail lane. It appears, as if the car sees the speed limit signs at the off ramp and tries to obey. I do not think the brakes were applied, but the energy recovery braking slowed the car down from 110 to 90, even the cruise control was changed to the setting of 80 kmph.
I believe, the auto AEB, as described in the previous mesage from rjpjink was set on as well.
I do have the FSD auto recognition activated though.
The auto steering, I guess its called here Autopilot (beta) was not activated as the feature does activate the high beams in a erratic fashion, which does not comply with my high beam behaviour, being more moderate with it. I really do not understand the matter behind this kind of operational need to take over the high beams for the auto pilot option. Is the car blind at night to operate to have the need for the high beams with this ?
