Yes I have the same thing and it's great. The radar cruise control allows me to stop being focused on maintaining speed and following the car ahead of me and let's me put more attention towards noticing traffic developments ahead, scanning the state of cars around me, and keeping an eye out for various hazards. I wouldn't want lane centering (as opposed to lane keep assist, which I have), because it would be too easy to shutoff and not pay attention to what's going on, and the window between realizing the lane centering is doing something wrong and needing to take over from it is too small for comfort given human reaction times.

Turns out, at least in my own personal experience, that’s not how it works. I don’t think this has been well studied, especially in the context of driving in a vehicle with gaze / attention tracking features. While my Tesla is working to keep the car perfectly centered in the highway lane, it frees me to focus on higher-level situational awareness during the drive. In particular, I find I can more quickly and consistently identify and avoid other distracted drivers, because I can look more closely at those features without drifting a few inches out of the middle of the lane. Just because you are not steering does not mean you have to disengage from driving. The focus on steering as a proxy for engagement is over-simplistic. Manual steering just to lane center can lead to “blind stare” which causes many accidents, so it’s a lossy proxy for attention / focus. As a new technology is adopted and people become less scared of the change, it eventually comes to a point where a new generation laughs at how things used to be done. What HN consistently likes to frame as a fundamental human limitation (“driving without actively steering can never be safe”) is in fact just a faulty assumption and purely conjecture in the context of a modern car cockpit with advanced lane keeping, adaptive cruise, object detection, and driver gaze & blink tracking.
