If the vehicle had these features built in by the manufacturer, and it was employer policy that the driver does not disable those features, would you still consider that to be a case of employers "judging" driving behaviour in real time? Or would it perhaps be a perfectly reasonable policy?

This is a monitoring system that helps drivers drive safer. Why are you assuming that it's anything else?

You're assuming "judgement" in a way that isn't related to driver safety that is not supported by anything in the article or the features themselves.
