Naughty Naughty Police!! Can't have them training to be able to get somewhere quickly if someone needs them urgently can we!?!
The maximum speed limit is 70 in this country, if the need to learn how to control their vehicles at speeds in excess of this they should do it off road, making race tracks the ideal places, the so called traffic can be made up of other police vehicles so it is safely controlled.
Screwing it down a motorway or an A road full of normal drivers, who are unaware what is going on, is asking for trouble and will at some point in time be the cause of a tragedy.
There are far to many idiots behind the wheel of cars on the roads with radio's blaring, and not taking enough notice of the rear view mirrors nowadays, without throwing high speed chase training into the mix.
