M9/M876 speed detector warning

[petercam]

Just a warning to any Scottish PH'ers travelling east on either the M9 or M876, there is a mobile unit sat on top of a bridge where these two motorways join. I think I have been caught myself 85mph.
Anyone else seen this this, and know what type of detector it was? I am assuming I need to roll over and take it up the ar$e, as it was forward facing, and they will probably have a nice clear piccy of me.
What really pi$$es me off is that I have had 2 instances of criminal damage from local scrotes in the past 2 weeks, and after the second instance (Sunday night), they are too busy to send someone round to take a statement (I have good descriptions this time, and even know where the scrotes live) They have the resources to sit a policeman on top of a bridge for several hours catching criminal motorists though!
My blood is boiling this morning
