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

Handhelds are LASER as opposed to RADAR.
Plus, for RADAR, there's a honking great lump of metal up front to give nice clear reflections through the GRP.

I don't think many forces are still using radar for handheld mobile enforcement these days. Laser is so much quicker, easier and more reliable.

(And unfortunately less detectable by the motorist)

And even then it's not very strong, which is why the owners of GRP boats tend to fit radar reflectors to make themselves stand out on radar more (very useful to avoid being mown down by a supertanker )

Ah, but you can deflect the laser with a couple of CDs and some blue LED squirty jets.

I've seen it done on a lorry.

Might kit the TVR out and become invisible.

Gatsos all work on radars, so might still be worthwhile...


Fitting a radar-reflector does rather assume that the supertanker has bothered to post someone on watch.

Wasn't this tried on a Mythbusters programme?

Tried everything to make a stealth car, even tricks which would make a pull 110% certain regardless.

Seem to recall everything failed. Could even detect a toy R/C car iirc.

But then they are Americans......

Yes, I saw that a couple off weeks ago.

Just drive everywhere at over 170mph, anything over that scameras don't flash as proved by Clarkson.

I dunno if this settles the argument, but:

I was accused of doing 92 in a 70 dual carriageway. Was zapped with an LTI 20.20 from 400m away.

Before you say it, yes... he did hit the front of my moving vehicle from a quarter of a mile away... did he need a tripod... nope...

Seeing that Dr Mike Clark has shown on TV that slip error produces errors if the car does not have a flat surface, you would have thought that the front of a Tuscan which has no flat surfaces would not get a reading... It apparantly does.

It is also correct that the laser devices are only tested on static, flat objects at up to 100m. Thus they also work at any moving curved shape at anything up to 2km.

Before you ask, the magistrates, and crown court judges were both in agreement that there is no problem whatsover with the conviction sticking.

The bottom line is: As long as the PC aims the gun in your direction at up to 2km away and gets a reading and decides it is your car he was hitting you will not win in court.

Thus in conclusion, as the machine is only as good as what the officer says. Also the government sanction the use of the laser on all vehicles at all speeds at up to 2km.

So, in effect, yes it does work. Whether it produces an accurate reading, and the fact that there is no proof that the targeted car is yours is irrellevent.

I hope that settles it, and is a warning for Tuscan owners, whether they are speeding or not!

At least Infrared you can seriously decrease the range of by having a car with a low frontal area, and painted matt black. All you need to do is work out a way to legally make the numberplate less reflective to infra red.

And were you doing 92?
