I often find myself becoming a sceptical old git in the presence of some of the new kit that gets loaded onto cars. I've still never found an electric handbrake that I like, or a keyless start system that beats having an actual key.

But a recent discovery proved that, to give a bit of credit where it's due, there are still some good new ideas being hatched out there. I was exploring the depths of the various sub-menus in an A4 Allroad's MMI system when I stumbled across a switchable headlamp beam converter.

This is a function I've been waiting for years for someone to invent. Frequent travel in Europe with right-hand drive cars is always a hassle due to the need to either get busy with some of those ludicrously fiddly stick on 'beam converters', or to spend any journey conducted during the hours of darkness being flashed by irate Continental lorry drivers who think you're motoring along on full beam.
