Tony Mernagh is right when he claims we will not persuade drivers to give up the habit of using their cars by hectoring, preaching or punitive charges (Opinion, 18 July).

The most effective tool in the campaign to encourage people to switch to public transport is to remove car parking places in the town centre and introduce more bus priority measures, rather than to create a park and ride site in the area of outstanding beauty on the Downs at Waterhall.

We could create park and ride sites in existing car parks at railway stations around Sussex so motorists could "ride" in by train.
