ibet they can, its risky.

if there is a stretch with 10 cameras, and only 3 lanes, you cant dodge them all, so id imagen they can still time you over the distance in any lane, even if it was on camera 1 and 10...

the m6 is full of the cunting things, adds at least 1 hour to my trip home to devon every weekend, and i havent seen ONE person working on them yet...i travel mostly at night aswell
