NHTSA Complaint #11507995 — 2020 TESLA MODEL 3

The ADAS system for the car includes automatic steering, which only works at the speed limit detected or less. The car incorrectly sets the speed limit in many instances as much as 30 mph under the limit. It isn’t safe to drive the car at such a different speed than the rest of traffic. Tesla claims it relies on map data and can read speed limit signs. Most rural roads have no posted limit, so they default to 55 mph. Even in the presence of a posted speed limit, the car defaults to their bad map data within seconds of passing such a sign. Tesla has no mechanism for reporting this bad data to get it corrected. This has been ongoing for more than a year.
