Features:
- Rush Hours in the morning and afternoon
- No slow cars if its rain and in the night. (thx piva)
- No stupid overtaking AI´s at national roads. (thx Todor Alin) (sharemods download)
- More traffic in the citys, (thx piva) but not to much, i don´t like it.

The AI's are friendly, but nevertheless it comes from time to time to accidents.
Normally it will be quickly resolved, but it can be also happens that you stuck. Therefore I recommend to quick save the game from time to time.
