I wonder if the software quality is lower for self-driving in non-US roads. I assume there would be less focus on development and testing in other markets.
I remember reading that Tesla can't recognize lighted or dynamic road signs (which are essentially a matrix of lights which change according to road conditions) present in parts of Europe because they're not present in the US to begin with.
Same signs were easily detected by a Ford Puma I drove recently on a highway.
I assume training data for European roads are also is of inferior quality due to amount of miles traveled and because of sheer variety of the roads, road signs and norms around Europe.
