Just want to share my recent experiences regarding a speeding ticket in Germany:

I was caught in one of those photo speed traps on a recent trip to Germany driving a rental car. Clearly noticed the flash from the camera as I was entering the city of Sassnitz . About a month later I recieved a letter at my home address in Denmark with a fine of 25€ for doing 65km in a 50 km zone. In addition to that , the rental company (Sixt) asked for 18.50 € in administration fees and the banks charged about 30€ in between them to handle the payment transaction.
So in the end, a fairly modest 25€ fine turned out to cost a little over 70€.
