First congratulation for the game. Game is gennerally pefect but I've some suggestions (I have played City Car Driving 1.2.1. for about 2 months now):

1. Many wehicles passages on red light, last time in modern district one bus is passed on red light

2. In mounthains part of game where have many places for overtaking, many wehicles overtaking very close of me and only way to avoid a crash is leap outside road

3. In rondabout, disturb me why all rounda bout not make on same simple way that say wehicles in roundabout have anteriority, wehicles that entry in roundabout must pass all wehicles in roundabout, it's very difficult look always on right side which road sign is for that roundabout

4. I say part of that on point 3., why road signs isn't on left side in roads with two or more traffic lane.

All suggestions are written in good intentions.

First of all, I am assuming you are German trying to write English . It's vehicles, not wehicles. Second of all, although these are all good points, it's very very hard to try to get the AI just right. In fact I've never played a game where the AI is perfect so expect some mistakes from the AI. In time though, I assume that it will be ironed out. Thanks for your suggestions I suppose.
