The other stuff Ed was talking about "ULEZ, road user pricing and pollution related parking controls".
You're asking too much to ask people to take individual responsibility for a negative externality, our brains aren't capable. Game theory has proven this type of cooperation to prevent pollution is not a viable equilibrium state.
The answer therefore has to be more tax on drivers and s tricter environmental standards. Maybe bring forward the ban on petrol vehicle sales to 2025 and raise taxes on petrol/diesel. I'd be in favour.
Not sure diverting cars from one big resi road (Valley road) to another (LCR) is going to make the tiniest difference to the number of drivers on the road but it does mean more traffic around some major schools. No "schools street" available when you're on a boundary road.
