Nick - I was talking to my boss about this... (since he handles these kinds of tickets before) He said he has seen that happen before. Seems that on really big traffic offenses that they tell you the fine... but then it gets run thru the local (German)court system. They all take add a little but more to your ticket fine.
One of teh guys I work with got a DUI last year. The Polizei told him he would loose his lic for one year, and have to pay 900 euro fine. But a few months later when he got his ticket thru his boss... the fine had jumped to 1,700 euros. Everyone wants a piece of you! lol

PS: What did that lawyer say that I gave you?
