There have been news reports about the model 3 autopilot getting its speed limits from maps, lacking any sort of sign recognition or manual override to adjust to local conditions. The maps seem to be outdated for germany (1). That’s an essential feature even on the autobahn. Given that test result I’d even be skeptical about any claims of being ahead of the game on the highway.
This is very strange though, is there any confirmation of this?
Basically, most other manufacturers like Opel, Audi, Mercedes, Hyundai, VW, Volvo, Ford, etc. has had for several years the feature to detect speed limit from computer vision recognizing the road signs. And it works reliably, as is pointed out in your link.
How can Tesla be a leader in using computer vision for cars, but not be able to read the road signs?
