I think you are mixing up motorways Rob

Well that's wierd. There was major publicity when the variable speed limit system was introduced (or perhaps when it was extended) about the centralised computer system being able to issue 30,000 tickets an hour. It doesn't seem like that would be possible with film based gatsos. They gantry camersa don't look like regular gatso's to me..

But then, that could explain how come I've never got a ticket on all the occassions I've been running late on the way to Heathrow.
