One possible solution to reduce air pollution in cities could be to bring the speed limit right down to 20mph inside cities and areas where there are extremely high levels of traffic congestion, ....or even as low as 15mph in some tight areas.......and get rid of traffic lights and pedestrian crossings.

Once the country has an infrastructure to be able to charge all our vehicles and a safe and environmental way of processing wasted batteries then it might be time to take the internal combustion engine off the city streets.
