A million people are killed directly every year by cars. Many more are seriously injured and disabled. Another million indirectly due to air pollution. They are also the number one cause of micro plastics around waterways. Billions are spent on hospitals, doctors, nurses, ambulances, police to support all this death.
Much more is spent covering our countryside on roads, that kill millions of animals every year.
And encouraging urban sprawl means cities take up more space, destroying wild life habitat.
This is just some of the awful things cars have bought to our world, not mentioned are wars, major spills, toppled governments, bribery, etc...
