I was pretty scared for my "probationary" period but luckily I didn't get any.

My neither. My 2 years just ran out, so I can worry less about getting done for speeding. There have been a couple of times that I've been hammering along the M11 and, in my mirror, seen a police car screaming up behind me, siren going, lights flashing, which has been a little worrying. Obviously, I frantically pull over to the inside lane and shed about 40mph in speed.

Fortunately, both times they were in a hurry to get somewhere else, and I'm not sure that they noticed how fast I was going -- I was keeping up with the flow of traffic, anyway .
