SIR – Talking of empty buses (Bob Dovey’s letter, October 16), between the two rush hours both First buses and Diamond buses go up and down Windermere Drive almost or totally empty. People simply prefer their polluting cars. Have you ever smelt a car’s exhaust fumes? They stink! No wonder asthma is increasing 10-fold lately. I say ban all private cars.
