    Human reaction time is ~0.25 seconds.
    At 20 mph, you’re going ~29 ft per second, so you go ~7.3 ft before you can react.
    At 25 mph, that’s ~37 ft per second, so ~9.2 ft before you can react.

    The internet says a good car can break at about 15 f/s^2.
    At 29 f/s, that comes out to a stopping distance of ~28 ft.
    At 37 f/s, that’s ~46 ft.

    So Anne, who’s annoying for some reason, needs a total of ~35 ft to stop just before hitting the child.
    Norman needs ~9 ft to start decelerating, so by the time he reaches the 35 ft mark (after ~26 ft of hitting the brakes,) it’s been a total of ~0.98 seconds, and he is going ~26 f/s, which is ~18 miles per hour.

    Fast food social media. Nice term there.

    Anyways, I don’t see why this has to be a matter of high privilege vs. low privilege. There’s definitely a correlation, but depressed rich people and happy poor people aren’t uncommon. Also, not all questions of positivity vs. negativity are in contexts that relate to privilege. It could be about the direction of a media series, for example, which is where I’ve heard it misused.
