I read your reply to JN of Midhurst in which you said you couldn't understand why people preferred analogue speedometers. The reason is very simple. With a digital speedo you have to actually look at the figure, which means re-focussing your eyes from the road to the instrument panel. This means that you are momentarily not looking where you're going. With an analogue speedo you're constantly aware of where the needle is in your peripheral vision without having to actually focus on it - rather like a primitive version of a head up display.

This was brought home to me vividly when I drove a 911 for a few weeks. The analogue instrument in the centre of the instrument panel is the tachometer, which incorporates a digital speedo, the analogue speedo being to the right, and normally blocked from vision by your right hand on the wheel. I lost count of the times I found myself speeding because I couldn't see the analogue dial and didn't want the distraction of looking at the digital readout. I would NEVER have a digital speedo as my main speedo again, and I suspect this view is shared by many others.
