I cant believe what you are all arguing about here!!
Have you not read the link that 'RufusA' posted???
This was a fatal crash on the M25 which killed 6 people, because a lorry was driving 19mph!!!
Anyone driving WELL under the speed limit on a motorway is really not quiet firing on all cylinders.
A speed limit is there not just as a limit, but as a guide for what speed is deemed 'safe' on that road.
Motorways are 70mph for a reason and driving anything under 50 is dangerous.
I also appreciate that it is the job of every driver to be alert and watch out for any potential danger.
But do we now also have to look out for George & Mildred driving at 30 on the motorway in the middle lane aswell!!!??
Just bloody amazes me some of the comments.
Ask a police officer/traffic officer they will agree that driving too slow is almost as dangerous as too fast.
I knew someone that was fined for driving too slow!!!!
Anyway my rant is over....
New drivers should have to take a motorway test i think, as there are too many nervous drivers that are a liability.
As for the knobs in 4X4's, BMW's & Audi's etc driving 110mph up your bum crack, well dont get me started on them.
I normally just dont move, i wont slow down as its a bit dodgy doing that if you are going above 70mph.
I also wont speed up, i just remain at my speed and stay there just to annoy them.
When they flash their lights in my mirror i flash them the bird.

Its so amusing watching some middle aged suited man get all stroppy cuz i wont move my little clio out the way!! ha ha ha
Yes i know its childish, but it annoys the hell out of me when i am only in the 'fast' lane as i am over taking a bloody middle lane driver in the 1st place!!
To then be flashed because i am there just is unbelievable!!
I NEVER over take slowly either i always make sure i am within the flow of the traffic so there is NO reason for these tailgaters to flash me or get up my bumper.
Stupid idiots, they never get much further.
