We've talked a bit tonight about unintended consequences, and one of the unintended consequences that hasn't been raised but that I would be concerned about is we already have issues globally about people not actually pulling over for emergency vehicles. It's actually one of my biggest bugbears. When I'm driving through the city and I see a police car or an ambulance come through and I see people not pull over, it really irritates me that people are not actually following the rules to ensure that people can be looked after safely.
