I decided some time ago to ignore all speed limits and decide myself how fast to go. It's worked really well so far, and I've had the cleanest period in my driving career. I'd recommend it to everyone!
I have always done this and have never had points. (Not quite ignoring speed limits, but using them more as a guideline.)
I don't know why people think dead babies automatically come out of the exhaust when you exceed an arbitrary limit posted at the side of the road.
Are people so stupid they have to be told how fast to go, rather than driving at an appropriate speed for the conditions?
