I am driving a Model Y LR 2023 in rural Washington State. Autopilot clearly does not understand speed limits out here. 50 MPH is the default unless otherwise posted. Instead, Autopilot sets the speed to 25 MPH unless it sees and recognizes (as it does erratically) a white speed limit sign. It does not seem to recognize a yellow 'Reduce speed to xx' sign ever. I'm concerned that it may be dinging my 'safe driver' rating as I'm mostly driving the real speed limit, 50, when Tesla thinks I'm in a 25 zone. Likewise, in '25mph when children are present'. It would seem to make sense to have a feature where users could report the actual speed limits to update the model, but there is no way now to contact customer support at all to suggest such, or find out if Tesla is dinging you for exceeding what it erroneously believes the speed limit to be. Google Map, by the way, knows much more about speed limits, as others have noted.
