I think it’s unfair to group all those features into “things for people who want to multitask while driving”.

I’m a decent driver, I never use my phone while driving and actively avoid distractions (sometimes I have to tell everyone in the car to stop talking), and yet features like lane assist and automatic braking have helped me avoid possible collisions simply because I’m human and I’m not perfect. Sometimes a random thought takes my attention away for a moment, or I’m distracted by sudden movement in my peripheral vision, or any number of things. I can drive very safely, but I can not drive perfectly all the time. No one can.

These features make safe drivers even safer. They even make the dangerous drivers (relatively) safer.

There are two layers, both relating to concentration.

Driving a car takes effort. ADAS features (or even just plain regular "driving systems") can reduce the cognitive load, which makes for safer driving. As much as I enjoy driving with a manual transmission, an automatic is less tiring for long journeys. Not having to occupy my mind with gear changes frees me up to pay more attention to my surroundings. Adaptive cruise control further reduces cognitive load.

The danger comes when assistance starts to replace attention. Tesla's "full self-driving" falls into this category, where the car doesn't need continuous inputs but the driver is still de jure in charge of the vehicle. Humans just aren't capable of concentrating on monitoring for an extended period.
