I READ your article on speed bumps (The Press, February 20) with great interest. I am also badly affected by their impact on my spine because I have a replacement disk in my neck.

The prosthesis I have has no absorption properties, so jolts from speed bumps can quickly compress nerves and cause pain. This makes life miserable as well as affecting my ability to do everyday things, including working.

I have written to the council on this issue but got exactly the same reply as the two women in your report.

There is some incomprehensible logic behind the use of such traffic-calming measures as they are a reaction to people breaking the law by speeding in cars.

However, they aren’t used on motorways where speeding is prevalent and they cannot be used on every road in York where speeding potentially occurs.

The other distorted logic is that councils pay out thousands (probably millions) in compensation to motorists who have had cars damaged by pot holes which cause jolting.

Strange that the council installs devices that are deliberately intended to do just that to vehicles.
