I was reading someone elses newspaper on the train last night (as you do) it said about microchips that are fitted to cars which record EVERY MINOR driving offence. So if you went 1mph over the limit, you are booked. Couldn't quite make out all the article, but even the bestest of drivers do things, forget to signal etc. I think that would cause an uproar.
The offences are logged and the first you know of it is whe you get a report through the post.
Oh it was in the Evening Standard, in case anyone else read it, can fill me in a bit! The guy turned over while I was trying to read it! LOL!
