Don't know if this has been posted before, apologies if that's the case. I was looking for the address for a fuel station recently and came across this site during the search:

Seemed quite interesting when reading all the information they have on speeding, get out clauses, plus a database of all the speed camera locations (although no longer updated).

Personally, I never speed in built up areas (I've got kids too) but never do 70 on a motorway
