Sir: If 'undertaking' on the road is to be legitimised, I hope it will lead to the reintroduction of the wing mirror, which, on the nearside in particular, gives far better vision than the currently fashionable door mirror.

The wing mirror is also safer - I believe it was in 1933 that Lord Haldane proved that wing mirrors can be scanned with peripheral vision, whereas door mirrors can be viewed only by taking one's eyes completely off the road ahead.

Yours faithfully,
