I was taught by a female driving instructor who told me to get to the limit as fast as possible, and stay there, even slightly over it, in order to show I was making 'satisfactory progress' along these roads.
I never could agree with her. It went against my nature, we used to argue about it.
Now on a dual carriageway (I don't do motorways) I tend to try and find a nice big lorry to go behind - not close up, but maybe a few seconds behind - and that way, I get to do a nice comfortable 50 or 60 while everyone else zooms past in the fast lane.
It means I can sort of hide with the lorry's restricted speed and they always have to go round lorries anyway so no one gets shirty with me and starts tailgating.
That's the worst thing - having someone behind you, so whatever happens ahead you just can't slow down.
The whole system sucks ass frankly. I really do think motorways ought to be for large vehicles only, at a restricted speed of around 50 or 60, no little cars - they should have their own roads, without lorries. It all wants consolidating properly.
The lorries are what caught fire. They are very prone to it, they get incredibly hot and their insulating materials are incredibly flammable, particularly the refridgerated ones.
I saw a programme about a fridge lorry that caught fire in a tunnel in Switzerland and so many people died. 
If there hadn't been the cars, the other night, very few people would have lost their lives - I believe at least 6 were in the cars.
