Yes, doing 45mph in a 25mph residential zone about 20 years ago. It was downhill, with a good view of the traffic, and about 200 yards of run-out at the bottom, so no safety issues with other vehicles. While I had chugged up the hill (original intent was just to get up the hill) a cop had pulled up on a short, undeveloped cul-de-sac at the bottom. I came screaming by him and he caught me and wrote me a speeding ticket. I went to court on and got it dismissed since the cop did not have a speed monitoring device focused on me to check my speed (he just guessed). I still have a photocopy of the ticket.
FWIW: This is one of the very few times I've gone fast on a downhill since I had some ideal conditions - I could see the route and the run-out area ahead of me, the pavement had just been resurfaced (nice and smooth, no potholes) and it was in an area that was just being developed with custom single-family homes with lots of empty lots (making for the great view of the route).
