when a unit knows it is stolen it will go into self destruct mode and explode wiping out two city blocks

That would clearly be ludicrous. Most cities in England aren't laid out in blocks.

If anyone stole an empeg in Cambridge, it would in fact explode wiping out seventeen Roman alleyways, four lych gates and a crypt attributed to Wren, the sites of two messy Saxon martyrdoms, and the floorplans of three rival medieval goose markets.

I was once asked for directions to King's College chapel by an American driving down Bridge Street. I was only halfway through explaining the Byzantine journey round the one-way system that was the only route would take him there, when he interrupted me saying "Cut the crap! How many blocks down is it?"

Figuring he had a few things to learn about Cambridge driving before he'd even be receptive to any advice, I let him go. But I felt sorry for the wife and kids in the car for the rest of the day.
