Dr. Who fan's life-size Dalek seized outside Parliament

So this Dr. Who fan named Ken Meikle constructed a full and completely motorized Dalek replica, then he gets inside, drives it over the Tower Bridge in London, parks it in front of Parliament, squawks off some pre-recorded Dalek jibberish, and gets promptly seized by a load of very threatened armed police. All in celebration of the new Dr. Who. So what have we learned? Daleks can still incite some serious fear in the Brits; use this very valuable information to your advantage in the future.
