Not sure it's entirely relevant, but I'm pretty sure that research done for instrumentation in aeroplane flight decks shows that information is transferred faster and more reliably from the instruments to the pilots when it's analogue. That's why even the modern glass/digital instrument panels have simulated "tape". They also include digital readouts for added accuracy, but it's the analogue versions that transfer in…
I disagree here. I find it much faster to read the speed from a digital speedo than an analogue one (especially as most cars compress the road legal range into under half the dial).
Especially in a 20 zones, a few mph is just a tiny needle movement but you definitely can get a ticket for it.
Analogue is better when your want to see something moving through the range though.
