If you're on a road trip, pull the fuck over and sleep. Your schedule isn't worth somebody else's life. If that's your commute, get a new apartment or get a new job. Endangering everybody else with drowsy driving isn't an option you should ever find tenable.
Maybe I wasn't clear. I've always stopped to take a nap when I had the inferior car, because I knew I was risking my well being and that of others. Ever since I bought my Model 3, I never had to.
As an example, after a refreshing 8h night's sleep, you put yourself at the wheel and you know you need to drive for 8h. After 2h, you'll feel the need to stretch your legs, have a bite, go to the toilet.
But if you have something like Tesla's AP, you'll still be alert and awake. Otherwise - at least for me, but I bet for many people - the constant nagging of micro-correcting the wheel, keeping the distance to the car in front, keeping the right speed, takes a huge toll on your mental resources, so much that it puts you to sleep whether you want it or not, and many people will try and push through that regardless.
You're saying that cruise and lane assist are dangerous because they're used to do bad things.
I'm saying they're very liberating from the busywork that is driving, and even people that use them as an excuse to stay on their phones are better off for it, because something more alert and precise is driving for them and as a consequence, less harm can derive from their stupidity.
I'm not saying that people that do stupid things should not be punished, and I'm quite happy that Tesla had to implement better driver monitoring. I know how things work and that I always need to monitor the system, but many people assume it's a magic button and disconnect their brain.
