REGARDING Ralph Ingham-Johnson's letter (May 13) about how the police go about law-enforcement is essentially a technical matter for them.

They are entitled to go about in plain clothes, or in non-specific cars.

Sadly, road dangers are not a myth.

Road casualties Great Britain and road accidents Great Britain show rising casualties in the mid-60s and onwards, especially taking "killed" and "seriously injured" together.

Deaths declined because para-medics carried more equipment in ambulances and underwent more training. The major factor, however, has been the serious reduction in walking and cycling as transport modes.

These are vulnerable, but benign and healthy modes. The decline is itself a pathological symptom.

We want safe roads not roads that are too dangerous for general use.
