If your navigation software says "Continue on I-50 for 350 miles", you will likely not need to touch the steering wheel for that stretch. If it says "Take exit 123 in 1/2 mile", you grab the wheel, take the exit, and let the comma take over after that decision. It feels more like a competent copilot than a full driver replacement.

What's the chance that a driver will sit there for 350 miles and not pull out their phone, fall asleep, or otherwise drift off while sitting for hours doing literally nothing but required to be fully alert.

Comma uses its driver-facing camera to detect is the driver is paying attention vs. looking at their phone or falling asleep. It chirps at you if you’re distracted and will eventually disengage if you’re not paying attention.
