What??? No! Driving straight is much safer. A potential collision of two cars at roughly the same speed is much less dangerous than a nearly guaranteed collision of a stopped car and a car at 120 km/h (75 mph). BTW Sweden has a low speed limit - it's 140 km/h (85 mph) where I live, but people regularly drive 160-180 km/h (~110 mph). It must go behind the highway border line if it's going to stop (and keep going if it's not possible!), but it'd be much better to pull out of the highway at the first opportunity. Definitely never just stop in the middle of a highway. Not sure if this is some kind of a US thing but here in Europe people don't expect you will stop in the middle of a highway. That's really extremely dangerous.

It's also dangerous to drive on the shoulder. Perhaps the safest thing is to keep going while it's obviusly just highway, perhaps a bit under the speed limit (low enough to get the attention of other drivers but high enough to not cause collisions). It could navigate to the slowest possible road and just park. Maybe drive with one wheel on the shoulder at 80km/h road on a 90km/h road, with warning lights and headlights blinking, car horn sounding etc. Worst case if the car approaches the end of the highway and there is a shoulder maybe it could stop there. After all, it's what any driver would have to do with a flat tire anyway (the self driving car can't run out and place a warning triangle 100m behind the car though).

What are you even comparing (and what are you even implying that my point is)? Sounds like you're comparing an automatic stop system to an ideal autonomous driving system. I was comparing stopping in a controlled way to what would happen if you don't have a system that control the car when you fall asleep at all. Obviously driving the vehicle like a human being would be the best option...

  The car is evidently fully capable of just going straight, so that's what it should do, never ever should it just stop in the middle of a highway lane. It would be great if it tried to pull to a gas station/rest point or, after a long time of very loud sound and vibration of the driver seat etc, and only if no other option is available, turn to the emergency stop lane and slowly come to stop there - but if these are not an option (the emergency lane is not wide enough, for example), it should just keep driving straight ahead at 80 km/h (minimal allowed highway speed in EU). If my car doesn't have autopilot and can't keep driving straight, I'd prefer a light crash to the right side to just stopping in the middle of a highway lane which is a nearly sure death sentence - and not just for myself.
