Not sure why people are so up in arms about it?
If you speed and get caught take it on the chin.
As for targeting just Brits? we have French friends whom have been do by the French Police for doing 4-5km over the posted limits.
Though the Police did explain to them that for that to happen they must have been travelling at 10kph+ over the indicated speeds and what was their excuse?
I have a Satnav that data logs (and no it does not have french speed cameras on it) if they said I was speeding I'd have evidence to prove it one way or another.
Most of these people in that article are not just speeding by 1 kph it's a fair bit more they don't really have a leg to stand on.
As for targeting super cars I wonder how many fines TopGear have had over the years? ;-)
