Have you tried going directly to autopilot without setting a cruise speed first? I haven’t specifically tested it but I notice that often the cruise speed is pre-set at the speed limit, so I wonder if you use that for autopilot if it will then automatically follow the speed limit.
Yeah, definitely doesn't work...it won't increase speed automatically by going directly into autopilot. I mean, it WILL...if you are in a 60mph speed zone, enter autopilot, speed zone changes to 40, AP slows to 45, and then zone changes back to 60, AP will automatically speed up to 65.
But if you start AP in the 40mph speed zone, it won't speed up automatically in the 60mph speed zone.
I learned that you can cheat it though. Lets say you are at a red light behind another car, in a 30mph zone. You start TAPP, which sets the speed to 35. You then manually scroll the speed up to 60, and then enter AP. AP states that your set speed is 35, but for the duration of your AP session, it will remember your previous TAPP setting allowing 60, and will automatically increase your speed.
However....that is ONLY for the current AP session. So as soon as you exit out of AP, due to any left or right turn which are of course extremely common city driving, it forgets all of your speed zone limits, and starts back at scratch.
Basically right now....yeah...its inconvenient that AP does not automatically increase speed, which I think it should (or Tesla should at least give an option for it). Yes, I agree that its Tesla being conservative right now assuming I DONT want to speed up in a higher speed limit zone...but that just seems wrong to me. If the speed limit increases, its actually DANGEROUS for the car to not speed up to the current speed that all other cars will move at.
Could they be referring to Model S and Model X that do have a separate instrument cluster where the speedometer is contained?
No..its the normal Model Y speedometer....and it does work correctly. Whether you are in TAPP or AP, if you touch the speedometer it will set the current TACC/AP speed limit to your current speed. So for example, if you are in AP and set speed is 60 but you are moving 45, if you click your current 45mph speed, it changes AP set speed to 45.
