When I was in the air cadets in Kilmarnock the parade ground doubled as the police "overflow" car park. One day a mechanic turned up looking for the police Sherpa minibus that had been sitting there for a few days. Story was whatever genius was driving this Sherpa minibus tried to pursue a Jaguar and blew the engine
My father was in the traffic police in the '60s. Main patrol car was the Austin 110 Westminster. Police spec ones were uprated and good for over 100mph but stopping it must have been "interesting"!
