Before Tesla switched the map data to tomtom (17.24.28, June 2017), my S90D would adjust speed when local road speed limit change. For example, when auto steer was set to 58 (55mph speed limit +3 relative), when road speed change to 50, auto steer will change the speed to 53 (50mph speed limit +3) automatically. This is very convenient and useful. Ever since the 17.24.28 update, I lost the automatic speed adjust function; and, my S90D does not show road speed limit on most of the major local road. Did Tesla change how auto steer setting the speed limit or my S90D have some sort of issue?
