Max Speed Offset’ 6 months ago Tesla updated FSD to v 12 on HW3 vehicles. Although I think V 13 on HW 4 vehicles are also affected just not quite as much. Immediately driving through any 25 or 35 zones the cruise would actually set dangerously high. Complained to dealer. Claimed couldn’t do anything as it was a software issues, would eventually get corrected. It did a little, happening less often, but still happened every time in small towns around me. When they changed it, the recommendation on the screen said go 40% over limit. I kept lowering my offset, no help. Lot of other people have been complaining on Tesla message boards. One person there said use 0% and that did work, but is annoying. I have included some pics. One showing the car set is self to 54 MPH when I drove into a 35 zone. The car read the 35 as it is on the screen. One with message about why they changed. They want the car to keep up with ‘flow of traffic’. Behind the pop up window you can see their recommended 40% over. Two pics messaging from tesla. Despite setting appt to fix it they claim nothing they could do. When I asked why mine did it all the time in some areas, no response. Last pic, my spouse doesn’t use FSD and the old system is still active for Autopilot and work perfectly. They could easily switch back. That area is still there, but greyed out in FSD screen. But they want their aggressive driver ‘keep up with traffic flow’.
