Autopilot (AP1 & AP2) in Europe (and Asia?) should change speed according to GPS speed sign database and not road speed signs.
In AP1 the camera can read the speed signs and show on the display. In AP2, while the car is showing GPS data for speed limit on the screen, in Europe, Autopilot does not change speed according to this data. Use GPS based speed limit data to change speed when on Autopilot instead of reading speed signs (AP1) unless the driver manually changes the speed setting.
Moderator: It’s been noted that some GPS database speed limit signs are way off the actual speed. AP2 in North America already adjusts speed based on the GPS speed database.
