Just to make sure that you really know about driving in Germany, please tell me what is the basic rule they use when driving around residential area other than the speed limit.
Hell if I know. I'm not German. In residential areas, I'm usually not going the speed limit or over it, as it's impossible to do it safely. The roads are either too small, there's too many blind areas, etc. Then ppl will also park in the road to make the road even smaller.
As for basic rule, as I mentioned, I'm not German. So haven't a clue. I've spent 5 years driving in the US, 3 years in UK, 1 year in Korea, 2 years in Japan, and 2 years in Germany.
