And what difference will that make in this case when you have fog and heavy rain and darkness? There will be the same accidents on the motorway regardless with the odd biggy like this one now and again. I dont drive on the motorway that much but the odd times i have in recent months i can honestly say the standard of driving in general is atrocious Poor lane discipline, driving to close to the car infront are the main problems i noticed and people not paying any attention to the driving conditions they find themselves in and chuck in the fact that most cant use indicators or the mirrors in their vehicles i am surprised there are not more accidents on this scale. What is it with Friday's and motorways? every friday afternoon the M6 near me is generally closed for several hours even in good weather between J15 and J20 because of a big accident!!
:edit: And forgot the fantastic standard of driving of some foreign lorry drivers using our motorways as well!
I do agree the limit should be raised in general too 80mph but that would not have averted last nights accident. Hope not too many people were killed last night or injured in this horrible crash though.
