According to the New Economics Forum (a UK think tank), owners of 4×4 (SUV) vehicles should be forced to display health warnings on the side of their cars similar to the health warnings seen on cigarette packs. We’ve already seen tax rates, licence charges and even interest rates on car loans linked to vehicle type so expect to see anti-car sentiment linked to specific government policies in the future. For example, large 4×4 vehicles could be banned from certain areas at certain times of day or local councils could offer free inner city parking for owners of hybrid, electric or small commuter cars.
