Mandatory eye tests for drivers over 70 being proposed by HMG. Good or bad?

[otherclive]

Whilst I agree that regular eye testing should be mandatory for all drivers, it would be too big a change politically - but once it is mandatory for over-70s we can campaign to get the age reduced.

Regular training and assesment would lose too many votes so not palatable politically, regardless of it's merit.

Whilst I agree with mandatory eye testing for older drivers, and encouragement of regular eye tests for all whether drivers or not. Has anyone given any real thought to the cost benefit of mandatory training and assessment every five years. We seem to live in a society that is chasing safety at any price and failing to heed the process of ALARP.
