london to manchester

[griff 1]

Guys, I need to drive from gatwick to manchester over xmas period. I expect the roads to be emptyish. If I go M25/M1/M6, does anybody know of any of those bloody cameras which measure speed over fixed distances. If weather good and roads empty I will do a safe 98 all the way, so any advice appreciated. Cheers
