The Rules of Not Being A Langer - a smaller rulebook to go with the Rules of the Road

As a motorist, cyclist and pedestrian, I’ve noticed it’s getting a bit cross out there. Technically the rules of the road should really be enough to keep all the different types of road users safe and happy but that doesn’t always work. I propose a much smaller rulebook go with the Rules of the Road — a summarising Appendix called The Rules of Not Being A Langer.
Based on no science whatsoever, I think there is probably a rough Bell-Curve distribution of people on the Langer scale. On the far left, there are those who are definitely not langers.
