As a happy EyeSight user, my feeling is that if it takes you any time to understand what is happening you are doing it wrong. These assistive features are great for easing the load of constant mechanical adjustments and mental focus on small details, but do not relieve you of being the driver.

I like to think about it like a ship. Having crew dedicated to rudder, throttle, and navigation doesn't mean the captain gets to take a nap. What it does is remove the distraction of focused attention required by those tasks, so he can be more aware of what is going on around the ship.

Likewise, with a car. With GPS prompting me advance notice of turns, I don't have to try to read every sign going by. With adaptive cruise control tracking the car ahead, I don't have to keep my eyes glued on that car just in case it slows down. And with lanekeeping, I don't need to concentrate so much on lane position. But I'm still the captain. I can't take a nap. I still need to be aware of those things, just not hyper-focused on them. Which frees me up to pay more attention to the cars and other potential threats around me. That greater situational awareness increases safety by improving my ability to anticipate and avoid bad situations, and means I don't need to figure out what's happening if I need to take over.
