In the UK we actually drive pretty well compared to most of the rest of the world. I think we have a fair number of good drivers who probably prevent a lot of accidents that would otherwise be caused by morons although there’s no stat that could ever prove that.
If you try driving around Istanbul, Karachi, Delhi or Tehran you’ll realise how good the UK is. In Iran they have 38,000 deaths per year from a pop. of 75 million but with fewer cars/journeys than the UK.
The argument over an 80mph motorway limit is pointless. I’ve spoken to several traffic cops from different forces who’ve all said, “Keep it under 90 and you’ll be fine.” How many people get done doing less than 90 on a motorway?
