Michaell- No they dont. If they clock you doing 71 the chances are your speedo is reading 76/77, not 66/67.

We're not big users of the M42, going to last years Autosport show the speed changed in morning traffic and a few cars in front of us there was a multiple crash, sombody braked for the reduced limit and four or five cars tail ended one another.
Thats not the speed limit , thats pratts driving too close to each other.
I drive around 600 miles per week, motorway, urban and rural. I Use the M42, especially the northbound stretch where vehciles over 7.5t are restricted to the nearside lane , and in this section the traffic flows much better.
As for the M25 , when i first used it many years ago it was bad, but at least once a week i *** down to Farnham from Sheffield and now find the M25 quiet easy , especially with the variable speed limits.
The biggest problem with the M25 are drivers hoping junctions, mums on school runs that sort of thing.
As a foot note, on Wednesday this week i was doing around 65 in lane 3 on the M1 , northbound between jn 44 and 45 ( i rarely get above 75mph during normal working hours as the roads are so busy) when i nearly ploughed into the back of a prat doing 55 in lane 3. cars in lane 2 were undertaking. The chap driving was probably mid to late 60's and simply did not have clue. Nice volvo, 06 plate , new swan neck and 12s/n sockets.
M ways need minimum limits not just max.
I was doubly annoyed as lane 3 is mine as i drive a beemer 320 at work and the volvo had no place being there. In fact i had to tailgate him and flash my lights to get him to move over. How dare he use MY lane.
