Speed trap between Beaconsfield old & new town

[alfa145uk]

Last night returning home, well about 12:30 this morning I came across a speed trap on the road between Beaconsfield old & new town... right on the corner (i think it's a school?) in the 30 mph zone.... I didn't get busted luckily... though I just think the laser zappers could have been earning more on a slightly more busy road as there wasn't exactly much traffic there at that time!!! Is that a regular midnight speed trap site?!
