I may be preaching to the converted here, but in the wake of Zak Carr's death and the injuries sustained by Emma Davies-Jones, I thought it timely to bring the work of RoadPeace to your attention. They're a charity that works with victims of and people bereaved by road-traffic accidents, and also campaign for the rights of non-motorised road users.
Have a look:

They do a great job. I'm sure you'll agree that any work to counter the way things are going on the roads in this country is to be welcomed and supported. Cheers
