I understand that airliners have separation between the computer systems used for entertainment and life-critical systems. That permits a less costly, lower reliability/testing standard to be used on the entertainment systems.
Unfortunately, current automobiles don't seem to have that separation:
In older models the speedometer and the tachometer were analogue but new Volvos have them digital so more likely to be affected by software bugs even when the separation exists.
I don't actually know how the analogue versions work or if they could still be affected by software bugs in the onboard computer. UI wise probably sturdier than digital I suspect.
