20mph speed limits

SIR – I have driven in a number of economy rallies with great success. Driving the first Volkswagen Golf diesel imported to the UK, I won outright against over 50 other entries , recording 63.5mpg over a varied route of 850 miles. I have also been Chairman of the Audi VW Service Dealers Technical Committee.

The case for introducing 20mph speed limits (Comment, June 1) is purely political. Let’s look at the reasons why these should not be introduced.

The most economical speed to drive a car is between 30 and 45mph, depending on the specification of the vehicle: four, five or six-speed gearbox or automatic.

They will increase bus journey times, meaning all bus timetables will have to be altered.

People who require a van or truck to work, such as electricians and plumbers, will take more time to travel between jobs. What about delivery drivers? Costs will have to increase.

The reduction in speed will also reduce productivity and therefore harm the economy.

Please let us keep the 30mph speed limits and only introduce 20 mph limits where absolutely necessary. Michael Stevens Gotherington, Gloucestershire
