IT seems to me a wasted opportunity when MG/Rover went bust that perhaps a government-backed company was not formed to create a car company to mass-produce clean cars that is, cars powered by solar power, backed up with dynamos behind each wheel and, if need be, air sucked in from the front of the vehicle through a small fan/turbine and out the back while driven.

No petrol, no water, just free energy.

Obviously, you would need batteries and they would in fact add the necessary weight to the car to keep it on the road.

In the meantime, we ought to have traffic-free Sundays, except for emergency vehicles.

Ban all night opening.

Cut back on aircraft movements and a lot more.

Then I strongly believe we would all feel healthier.
