I've got a question about how to drive the car in Europe on Highways. In the US, I can overtake another car on either side, and I am fine.
In Europe I was told that I have to drive on the right side (Germany), and to overtake on the left side of the other driver.
Now I had following situation, and I did not know how to handle this properly: I was driving along on the right lane, the Autobahn was 3 lanes wide on my side, and was going around 110 km/h. Someone overtook me, but he stayed on the middle lane, and suddenly got slower. He wasn't really in front of me, so I could not change to the left lane, but I was told I may not overtake on the right side.
Would I have to brake in such a situation, or should I just ignore it, and overtake him again on the right side?
(I overtook him, and he was on the phone, so I guess that was why he got distracted and slowed down that much).
