as a piece of advice :
DO NOT STAY IN THE LEFT LANE IN GERMANY AT ALL TIMES UNLESS IN A MIG21 !!!
Germans are used to driving at high speed, they did it all their life(no, your UK experince does NOT compare...). its the foreigners like you, that cause accidents cause they watch in the rearview mirror how u get closer and still dont get a clue that it might be time to get in another lane..... What they do is they flash headlights which means : get out of my way.... suggest u do it next time if you dont want to kill yourself and people around you.... I lived in Frankfurt and had an Audi S4 at the time, still there were people that i had to give way at 300km/h...thats germany m8
