I wonder if this sets a nasty precedent?
Dont know about nasty....certainly interesting. A couple more like this could have huge implications with the extreme end being our motorways become unrestricted autobahns.
Personally; I'd be trying to use this as a case law if I was clocked a bit over the limit on a motorway with little/no traffic around. If you're going to lose your license anyway, why wouldnt you?
For the record: I don't have any points on my license, but have had a couple of camera tickets of just over the limit in the last 10 years.
