Why sat navs are a conversation killer

When my daughters learned to drive, I suggested they take their tests in automatics as driving manual cars would soon be redundant. I worry about this. Not because I think I was wrong, but because I fear that gear-changing is yet another of those once commonplace skills which may soon be lost to technology for ever, like double-declutching or the ability to memorise more than three phone numbers.

As evidence of this depletion of tacit expertise, consider how the satnav has eroded map-reading skills in anyone under 40 – something which might explain why the Russian army sticks to main roads even when driving tanks. Since nobody uses printed maps any more, it has left people spectacularly ignorant of relative geography. One friend’s son recently left his parents’ house for London to cadge a lift to a concert. Nothing odd about that, except his parents live in Taunton and the concert was in Devon.
