I have no idea how well such a system works, but, I found these lines pretty jarring:

> They found it fires on ordinary driving, not just distracted driving.

> Glance away from an empty highway to take in the scenery, or look at the infotainment screen to change a song, and the warning goes off anyway.

Like, isn't that the point, that if you aren't looking at the road it should go off?

It's bad though because glancing at your side-view mirrors is good, but this will train drivers out of it by beeping at them because their eyes aren't perfectly forwards-facing.

It's an overly simplistic solution to a complex problem, that also coincidentally helps advance the surveillance state more than it does help prevent distracted driving.
