What's your top speed?

You need to present a high enough Radar Cross Section. I mentioned it a few pages back. There's a speed camera on a hill on my way back from uni and when traffic slows to 30, I can easily get past them at a high enough speed to set it off, but I can't actually set it off. I've often thought of carrying a big board on my back but then I've thought the drag would either stop me going fast enough, or stop me fitting in between the cars, thus defeating the point of it.

I have exactly the same thing on my way home from uni, still haven't managed to set it off, either have my mates, we've had times where we lead each other out and still no flash, think 37 is the fastest I've been past it. This is all on geared bikes mind, no chance on my fixed gear.
