Yes, I'm in favour of 80mph speed limit, along with enforcement of a minimum speed limit as well, because I see many cars doing 40mph in the slow lane these days when the traffic is free moving.
It's frankly dangerous to drive so slow that lorries have to move into the middle lane to pass you.
Yesterday I was stuck behind a transit on a two lane section of the M65 that was maintaining a steady 45mph, the fast lane was clogged and no-one would let me in, when I did manage to pass him the road in front was clear, so there was no need at all to drive that slow.
wiz-king is not wiz as Noldi has pointed out. I am miles away from doing as our Brussels masters dictate but at least they are more sensible on this one!
Accidents are caused by bad driving, not high speed.
The M25 you can consider yourself luck if you are doing 70MPH and that goes for a lot of the other motorways in busy periods.
I think leave well alone, I do a steady 70 with the cruise control on and at times I feel like the slowest car on the road, I can imagine what its going to be like at 80 when they start doing 80-100 and things happen a lot faster at those speeds, especially when things go wrong.
I recall the days when car manufacturers use to test drive their cars on the M1, when in its infancy.
Looking in your wing or rear view mirror's, and seeing a car in the distance, then a few seconds later a vehicle passing at high speed, and a few seconds after that, the vehicle was gone, wasn't a very pleasant experience for the average motorist. Perhaps a big thrill for the car tester though.
But having stated that, I could never recall any reports of any accidents through that.
I'm not boasting, but there's something very satisfying about passing a police car at 80+ and then changing up (my BSA did 90 in third)!
Non-urban speed limits were originally introduced on fuel economy grounds, not safety.
I don't think Germany's motorway accident rate, where there is no overall limit, is significantly worse than ours, though obviously any accident is proportionately more severe and the the fatality percentage will be higher.
