MR Delaney (letters, August 7) suggests that speed causes only 7.3 per cent of 'accidents'.

Surely it is 7.3 per cent that are not caused by speed!

As for the Mortimers Cross junction, the locals should collect money to buy a few old but road-legal cars, which could then be parked near the junction to create chicanes so that the motorised idiots would have to slow down - 24 hours a day.

The locals could act now, before people are killed.
