First up, the speedo is not only about the number, but also the position of the needle. I don't need to know if I'm doing 110 or 111, but the position of the needle will tell me at a very quick glance if I'm venturing towards 120 or slowing to 90
Second - I thought we'd decided adjusting volume by anything other than a physical turning dial was a poor way to do it about 10 years ago.
Then there's other odd things like 83% oil - what sort of use is a figure like that? Is that good or bad? Oil pressure is what I need to know, and even then a simple binary ok/not ok is sufficient
Possibly the main problem is that there's not really much wrong with displays as they are. I can see my speed and rate of acceleration, rpm, warning lights etc at a glance. I can dim them to my liking. And, importantly, anyone else driving one of my vehicles can very quickly acclimatise themselves and feel confident driving it. With the way things are currently, there's really only two things I need to figure out when I hop into a car i haven't driven before - which side of the steering column the indicators are on, and where the headlight switch is
