Madam, - A 60kph speed limit is currently in force on sections of the M50 to facilitate road works. But drivers who keep to this limit will be overtaken at high speed, and will experience tail-gating and gesticular abuse. May I suggest to Mr Noel Brett of the Road Safety Authority that these limits be either enforced or abandoned?
- Yours, etc,
PATRICK O'KEEFFE, Clonard Grove, Dublin 16.
