im looking to do a journey up the m1 tomorrow
drove on it a few years ago
rigged with cameras lots of average speed checking ones
you mean 50...
lol
Theres two sections that are clearly marked, with big huge yellow speed cameras everywhere, and everybody around you will be doing 50.
Just sit in the middle lane and follow the flow of traffic and you'll be fine.
Then just floor it the rest of the way.
I drove from london to leeds the other day and did most of it at 85. Just make sure you slow down for the roadworks. Simple really ?
Theres a bunch of fixed cameras between junction 24 - 26 as well.
