Volvo recalls all of its 72K EX30 cars due to software bug that obscures speedometer
(www.theregister.com)
This is a most excellent place for technology news and articles.
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.
