There's definitely something borked with our brains though. I have had multiple people express surprise when I tell them that I will not check any notifications when I'm driving even if I'm stopped at a traffic light for a minute or more. I just don't want to be distracted, and yeah it takes conscious effort sometimes, but it does get easier once you learn from experience that the world will not fall apart if you check your messages later.
I even internally reframe it as future candy, which makes me engage more positively with async interactions. But practicing delayed gratification is hard.
