My car has a regular dashboard with analog indicators for oil pressure, water temp, fuel level, and voltage. The analog indicators ( a red needle) are easier to read at a glance than digital displays. But it could be better, for no cost increase.
The gauges could be marked with real numbers instead of just H and L. This way you would have something meaningful to pass on the the mechanic on the phone.
The scales could have a green band to show normal and proper levels. And a red band to indicate trouble. And they could be arranged so that all the needles point up at 12 o'clock when things are good. That makes a quick glance at the instruments more meaningful.
Too bad the stylists rule in Detroit.
