Spook says: Oh no, I'd better not speed to disarm the nuclear weapon and save the world in case I get a ticket in the mail in 2 weeks time!!!. Oh no, IT'S TOO LATE!
Spook says: Fear not, I shall go 35mph in a 30 zone and SAVE THE WORLD!
The fact is that the Police cannot speed whenever they please, they have to be on a recorded "emergency" incident, and unless the records support the need for the "blues and twos" then the driver will very much get a ticket. So how is this going to work with a spy? Are they going to write down the top secret terrorist incident they were speeding to in order to get away with a £30 ticket? I think not.
Alternatively, if they are caught by one of the very very few remaining police with the power to pull over a vehicle (rather than simply being flashed by a robo-enforcement scamera) how are they going to answer the plod when he asks "Whats all this about then?" Are they going to say "sorry, you can't give me a ticket but I can't tell you why you can't give me a ticket?"
Waste-of-time legislation....in fact I can't believe I wasted my time typing this.....
