Chris Gould (Letters, July 30) suggested the answer to our congestion and pollution problems is for everyone to get off buses and into cars.

Official statistics show 56 per cent of the total atmospheric pollution over Britain is produced by car exhausts and less than 1 per cent comes from buses and coaches.

At Brighton & Hove, we have been voluntarily fitting particulate traps to the exhausts of new buses for some years so reducing such emissions to almost untraceable levels.

On average, a bus carries the same number of people as 30 cars in a tenth of the road space. We move about 100,000 passenger journeys across the city each weekday.

Is Mr Gould seriously suggesting we'd have less congestion if these were all made by car?
