comment How are digital speedometer readings typically calculated?
@RoryAlsop - Good point. I never actually said my reason for asking this question, but basically I like cruising smugly past people on average speed checked sections of motorway. :) It looks like I can sit at 57-58mph on the speedometer (a true 52-53mph) and not get a ticket, lol.

@mac - Yeah. Wish my car had a real-time digital speedometer that I could compare to speed on GPS. I guess I could always set cruise control at 50mph on the speedo and compare it to the value read on the trip computer. Or time a distance.. but then I'd expect it to be an increasingly larger differential the higher the speed... Ah well, it's no big deal. :)

So how accurate might that computer be? Do I assume that the 54mph showing on the speedo is just 50mph (the speed shown by the computer) marked up to compensate to give drivers a bit of 'headroom'? I just want to know what speed I'm actually going! lol. And would the tyres being over/underinflated impair readings?
