I AGREE with Mrs M Ash (Letters, Friday, January 10), road humps always aggravate medical problems for people suffering from spinal and back pain problems.

They also reduce response times for all emergency service vehicles, such as Police, Fire and Ambulance. For these reasons, all road humps should be removed completely, wherever they are, and all residential side roads to be restricted to 20mph speed limits, enforced by the usual policing methods.
