Sir – I sympathise with F. Boyce and his injury after a trip on the paving stones in Oxford (Letters, August 15).

Has anyone done a survey of the uneven paving in the city recently? While waiting for a bus in Magdalen Street last week, I saw approximately 90 people walk past, six of whom tripped, but fortunately did not fall, on the paving stones.

If Oxford is to become a no-car, no-bus, pedestrian-only city, the pedestrians need to be provided with a safe surface on which to walk.

Replacing all paving stones with Tarmac would be expensive but uneven Tarmac is not so easy to trip on and less painful in the event of a fall. I have the scars to prove it.
