I know the weather probably played a huge contributing factor but the standards of driving on the motorway is shocking, although I find 70mph to be tedious at times considering it was a limit brought in when your average car would have wobbled up to that speed and struggled to get back down I believe raising it to 80 would cause chaos. There really needs to be proper education, motorway driving should be a compulsory part of learning to drive (possibly incorporated the same way pass plus is once your test has been passed). It's amazing you can pass a test without using a motorway, utter madness.
