More painful to manage turning it on/off than to simply leave it in my car.
Over the years, I've spent far too much time with different solutions for managing notifications, etc. Turns out simply keeping the older phone after buying a newer one was the easiest approach. No downsides so far. The old phone has the SIM card. The new one doesn't.
Looking at the phone, disabling the lock, swiping down, and pressing "Do not disturb" is a lot more than just not looking at the phone.
Also, that's only half of it. I have to move it out of "Do not disturb" at some point. Or set a timeline for it. Why should I when I just don't need to?
Also, it's been years since I used "Do not disturb". Does it show notification icons in the drawer on top? That's a definite no-no.
