It's definitely not a solved problem in the real world. Eye tracking in the lab works great but in the real world there are lots of challenges. Low light levels at night, drivers wearing sunglasses, drivers squinting etc.

That's solvable: if it can't see your eyes, then you can't use Autopilot. That should still let the majority of people use Autopilot the majority of the time.

I want to wear sunglasses.

Further than that, if you're driving west at sundown it's much safer to be wearing sunglasses than squinting.

Then you can't use Autopilot. Where's the confusion.

Making sure you're at least facing in the correct direction (chin up, facing forward) would help even if sunglasses prevented locating the actual gaze target.

If you still want to use your phone, it'll be easier for the cops to catch you doing it.

Your desire to wear sunglasses is a lower priority than the health of the people you share the road with.

So being blinded with autopilot on is safer than being able to see, but allowing the possibility of inattentiveness? That's ridiculous.

No. Your assumption that I'm saying that is, frankly, ridiculous. If you're being blinded, put the sunglasses on and turn Autopilot off. Of course, I doubt that eye-tracking works particularly well if you're squinting and averting your eyes anyway: the act of being attentive precludes being blinded in itself.

Why would the attentiveness monitor be tied to autopilot? Some modern cars without autopilot already have attentiveness monitors. It's ridiculous to require people not to wear sunglasses. Just for the sake of attentiveness monitors. Anybody driving east to west in the afternoon or west to east in the morning wouldn't be able to use it at all.

GM's Super Cruise has eye tracking [0]

GM's Super Cruise uses an infrared camera so it can effectively see through most sunglasses. Some glasses do block infrared light too so the Super Cruise system doesn't work in all cases [1].
