I recently bent my car against a protruding tree trunk. It happened very suddenly as I was attempting to make sense of a concealed road sign approaching a roundabout.

The reason for the concealment was an overgrowth of vegetation.

The incident did not occur in Bristol, but Bristol is far from blameless in this respect.

A clockwise run round the A4174 in daylight will provide a menu of examples. Bus stops too, tend to disappear into people's hedges.

Inevitably, as we drive on the left (until the EU decides otherwise), it is the left-hand turn destinations which vanish first; and when there is more than one option – hard left and fork left, for example – the opportunity for confusion, hesitation, and road rage by less understanding drivers approaching from the rear, is endemic.

There is a full-time job waiting in the wings in the solution to this breach of elf 'n' safety strategy.

It's not rocket science.
