Average speed cameras

[cleanbluesky]

Was on an M6 jaunt yesterday, and noticed average speed cameras on the motorway roadworks - although what surprised me was the amount of people driving through them above 40... especially at night.

Do they know something I dont about these cameras?

Have you checked you speedo against a sat nav?

Your car maybe reading less than your actual speed by a few Mph

I was going about 38-39 on the SatNav and they were overtaking between 5-10 faster...

It's probably just the tolerence levels then, I'd have thought being average speed the tolerences would have to be higher?

I dont think that there are any rules with regards to getting caught speeding, plus these are new technology so there may be new legislation for them...
