Owner's description
Upon purchase of the vehicle, unlike previous models and versions of the software - the vehicle’s speed limit control was incapable of being set - instead, using FSD, you had to select from percentage based offsets - which were frequently ignored and would still go much higher or much lower than the percentage value set. The owner of the vehicle was unable to say limit to only 10 over the speed limit; instead it was percent based and not reliable. In addition, more than a third of the time - the speed limits in the infotainment system did not match the posted speed limits. Sometimes, in the middle of a highway - it would randomly go from 55 to 25, posing a significant threat hazard when using the FSD or cruise control system (which is something Tesla charges extra for access to) causing the vehicle to immediately decrease speed when other vehicles behind are getting up to speed and not expecting a vehicle to randomly slow down excessively. Additionally, when you manually override the speed limit control, or the system does, the user interface hides this limit so the driver is unaware of what limit of speed it is set to. These issues were already bad enough, but just yesterday my vehicle was pushed a software update that dramatically reduced the performance of FSD, and now I am unable to manually control the speed limit at all in FSD. This was a regression from purchase, when a scroll wheel at least allowed me to manually set the speed limit or correct it when it was wrong. Now, that feature has been removed and instead there’s a duplication of FSD profiles (left/right on the right scroll wheel does the same as scrolling up/down). And continuing this trend, the driver is incapable of seeing what the speed limit is set to because it’s hidden from the user interface. In addition, the driving behavior for FSD has significantly regressed from before the update. Cruise control’s most basic functionality should be to set a speed limit. Now this feature has been removed.
