That may well be the case Dave, though as North Yorkshire has no fixed speed cameras but the largest fleet of speed camera vans in the oountry, more chance of one up here being speed rather than APNR - mind you, they could be both !
North Yorks Police were on local TV a month or so ago saying that they were having a robust anti-speeding campaign this summer - not worth taking any chances there.
Of the 3 vans I saw, one was on a straight de-restricted road (plenty of warning from on-coming traffic), one was in a 30 limit where there was bugger all chance of actually getting up to 30 (sop to the locals to be "seen to be doing something" ?) & the last was "re-positioning" as was a few vehicles in front of me.
I would have to be trying hard to attract the attentions of one on the Classic, though.
