I've now read the entire transcript and it was impressive. Odd, too, because drivers in Scotland - from top to bottom, are, in my considerable experience, considerably less watchful and a deal more aggressive than drivers in London. But here we have people discussing a matter that might (or might not) make a huge difference to cyclists and pedestrians, entailing a considerable change in the law.
In 1975 and 1976 I spent some months in Vancouver. They had a variant of strict liability. Car insurance was state owned and would not pay out if you drove in to a pedestrian. The result was a kind of pedestrian nirvana . Vancouver seemed to me to be the high point in civilisation (and the girls were pretty). If strict liability had a similar chilling effect on the drivers in Scotland it would be the happiest of days.
