Cars are one of the biggest pollutants. Yet I would rather get the bus but it doesn't work out any cheaper than the car so I drive. People that get the bus are also fitter as they walk more.
My parents get free bus passes, but this doesn't stop them driving that much and still both have a car.
Buses are empty, cars are clogging up the roads and air pollution is above who guideline levels in many cities in the UK.
