I have proof of getting away with speeding - you just need a vehicle faster than theirs and false plates*
* Do not try this when the helicopter is up!
** I might have made this up if anyone gets seriously upset.
I would add a hired Mustang GT in Florida is no match for traffic cops in a helicopter !!
In 1990 I was asked for my ID, by a policeman, while refuelling ...
not a problem I thought and when he said I was doing 75 in a 55mph zone, I was puzzled
Until he pointed skywards (and then gave me a fine) .... a police copter was hovering overhead, it had followed me and got me over a timed distance !
