On paper it's brilliant, we have the EW(Scotland) Act 2005 which should allow prosecutions to be brought to be bear if someone doesn't pull over when you're behind them. Unfortunately, it's incredibly hard to prove out on the road. Hospital staff have an easier time of it because of the number of witnessess/CCTV. Sadly, in my experience, police are less keen to charge people on it because they're not used to the way that it applies to other organisations, differing as it does (and please don't ask me how it does!) to obstructing a police officer, etc. Kal (law librarian this month, hopefully EMT by August!)
