I think that the "someone you know" was very lucky.
When I was nicked some years back I was only doing 26 MPH over the limit, and that meant I had to go and grovel to the Magistrates.
Years ago I was told that anything 30mph or more above the posted limit was instant ban territory, but this may be poppycock. Ill have to ask my policeman mate (but hes on holiday and Im still waiting for him to answer my question about the correct wearing of uniform & number of officers required issues that were discussed here a couple of weeks back).
I think its still 3 pionts for a fixed penalty ticket.
