Can some body help me settle an argument please

[gib6933]

My friend and I were talking about these money grabbing devices the police are using to distract us and ruin today’s roads (speed cameras), we were thinking of a way around something like a stealth car and my friend said that all thease radar guns will not work on a tvr because the body work is grp I do not agree with him. So has any body been mugged by the police with a hand held radar gun driving there tvr?
Please help


thanks Jez
