We don't have a general speed limit on German highways, the speed driven in the leftmost lane frequently exceeds 120mph by a lot, so the differential speed between cars in different lanes can be quite high. While you are driving 80mph (130kmph) in the middle lane a car will pass you at 130mph (210kmph).
This only works because one of the rules on the Autobahn is that - except from a few circumstances - you are supposed NOT to overtake on the right. The lane on the right of you is always slower than your lane.
So I'm wondering
- does the autosteer-feature of tesla obey this rule or will it pass by a slower car on the right
- when auto-changing lanes to the left, what is the maximum speed difference the Tesla checks for (i.e. how far back does its radar / camera-system check whether a car is approaching).
