I got "blitzed" in Bielefeld on June 4th at night. The speed limit was 100 km/h until 22.00 and then goes down to 80 km/h until 6.00.
I was nailed at 94 km/h after the speed limit drop because I couldn't read the times on the sign (going what I thought was the speed limit at night) until it was too late. I saw the flash and figured they'd try to stick my rental car co. with the ticket, who would then charge my credit card. Co-incidentally, it was my wife's credit card, which has no foreign transaction fees and she had it canceled for fraud a few days after my return. I never heard from the rental car co. The nastygram from the City of Bielefed is dated July 29th, I got it today and I was to pay a 20 Euro fine within a week. Obviously, I'm way late and I think my bank charges $40 for a foreign wire fee anyway. So I won't be paying this one. Flame away.
