I'm pretty sure Tesla isn't using the TomTom map data, but I could be wrong.

What do you think Tesla is using?I'm pretty sure Tesla isn't using the TomTom map data, but I could be wrong.
I don’t know what they’re using, but it was wrong before and is differently wrong now.
Tesla hasn't officially confirmed this... So, like most of Tesla's software, we're just guessing on this.
It appears Tesla switched speed limit data providers last summer - moving to TomTom.
The TomTom data appears to be much worse than the data from the previous provider, with more areas with missing or incorrect speed limits.
While they appeared to update the speed limit data recently (a local road that was marked for 55, which has an actual speed limit of 40, has been corrected), the current speed limit data still has a lot of problems. And this can affect operations - especially when running under AutoSteer on highways and the speed limit data incorrectly believes the speed limit is much lower, causing AutoSteer to immediately brake in the middle of high-speed traffic.
This problem is compounded by the lack of speed limit sign recognition for AP2 cars.
Because of this, you should be prepared to re-apply acceleration whenever you are operating under AutoSteer, in case the software decides to brake quickly (which is also true when AP2 detects a phantom object ahead, and tries to slow down).
Obviously not a sustainable situation. I wonder when and how Tesla will resolve it.I just did a road trip to Yellowstone from Colorado this past week and speedlimits were incorrect about 70-80% of the time. It's painful on the two lane roads. Can't use Autopilot for 100s of miles at a time because the limit is 10mph too low.
Also, I can't use AP to/from work anymore since all the limits are 10mph too low as well. Hoping they get the Speed Limit Reading update pushed sooner rather than later.
Agreed...Speed changes are very abrupt. I'm not trying to get rear ended. I know most states auto fault the tailing car but I still won't have my car for weeks or months.If I were programming the AP that was blind to the posted speed limits and went strictly by the geodata, I would say: "if no speed limit is available for the road segment, assume the same speed limit as the last known speed limit". Not "assume speed limit of 45 mph".
If (and when) I get my Model 3, I am prepared to drive with EAP engaged in the beta tester state of mind, with a foot near the pedal and a finger on the TomTom app ready to report the missing speed limit, and another on the voice command button to report the same issue to Tesla. One can see fun in that. Then again, one may only want to engage in this type of driving under safest of conditions.Agreed...Speed changes are very abrupt. I'm not trying to get rear ended.

Is creating a voice "bug report" understood to have any (positive) impact, or could be a waste?
Is adding speed limits via TomTom's Map Share™ Reporter understood to have an impact? Does TomTom accept these changes? Are they propagated to Tesla in a timely fashion?
Thank you for clarifying that braking for phantoms and braking because of a missing speed limit are two separate issues.
Are you on AP1 or AP2? My car (AP1) will read the posted speed limit signs and adjuste AP accordingly, which is great unless you pass a school zone when school isn't in sessionI just did a road trip to Yellowstone from Colorado this past week and speedlimits were incorrect about 70-80% of the time.

My town has put up "Speed Limit 25" "Unless otherwise noted" signs. They are on the same pole, but 2 physically separate signs. The AP cameras ignore the 2nd half of that, and slam on the brakes, because it thinks the 45 just dropped to 25.
It is a little scary that we have an autopilot based entirely on Vision which can read numbers, but not letters!
