I know the motoring law.
I can read speed limit signs.
I can keep to the limits.
I do not want to be checking my speedometer more often than I am checking the road.
Stop adding average speed cameras when you re-build motorways; people start breaking and acting irrationally when they see average speed cameras.
If other countries can regulate themselves on the roads without speed cameras, I'm sure we could – we survived without them in the past!
