Helen, a.k.a. Mrs Vole, who spends more time on the internet than most, with a focus on transport (some people do have strange girlfriends), comments on how the crash is discussed in rather contrasting terms, comparing news websites and cycling forums. On the news, the focus is on the fireworks display, the smoke, fog, poor visibility, rain and wet road. On the cycling newsgroups, they talk about speed and tailgating. In those discussions there is understanding of the concept of "contributory factors", whereas the general news channels look for the "cause" of the crash.
I sometimes think that perhaps all the most intelligent motorists are cyclists – at least part-time cyclists.
Hopefully there will be one last casualty of the M5 crash: the government's idea of increasing the speed limit on motorways to 80 mph (129 km/h).
More on this in a good article from Peter Willby in the Guardian: "Ministers are nudging drivers in the wrong direction".
