Based on the photo included in the article, what they're calling an infotainment system is actually two separate components, one of which appears to be taking the place of a traditional dashboard. If that's the case and there's no other way to monitor speed, fuel levels, engine temperature, warning lights, etc., I'd say that's quite a bit more worrisome than just not being able to play your favorite music while driving.
I understand, but the risk of life wouldn't be from the bug, it would be from conscious choice of driving without a speedo. There's a critical distinction there.
In this case, mileage/battery are still present, and I would assume safety critical warnings would still be displayed.
That any car can have a dead
/failing battery/fuel pump/whatever one morning or fail and leave you stranded on the road to an hospital has never been considered a safety risk.
