No, I am paying attention. Why don't you check the math instead of just assuming it's wrong and making yourself look like an idiot who thinks I must have made a mistake just because I referred to something that used meters.
World record for 50m dash: 5.56 seconds
50 meters = 164.042 feet
World record = 0.03389 seconds per feet
20 feet = 0.68 seconds
So what I said is absolutely correct, that the claim is that the average person will run 20 feet at 2/3rds the rate of a world record sprinter (actually, a little higher). The sprinter is starting from a dashing position, wearing sprinting shows, is on a track that's conducive for sprinting, and is well beyond the median in capability for sprinting. And even they would probably struggle to hit 20 feet in under 1 second given that it's such a shorter distance than 50 meters - you just have to look at how much worse the speeds are for 50m world records vs 100m world records, because you do spend some of the sprint accelerating. So it's very unlikely that the average person will cover 20 feet in < 1 second under any kind of normal circumstances.
As for the other stuff you said, you have to understand, I'm not saying the guy was wrong to draw his gun - he knew what he was doing and I give him the benefit of the doubt that he won't needlessly shoot someone who is a threat. There IS a non-zero risk of a gun actually escalating a situation (if the other person is armed, or if it increases the chances of him coming after you if he sees you later), so it's not just a given that it will de-escalate the situation. But the real point in what I said is that I wasn't convinced enough by the situation that I would have felt I needed a gun, and so am not convinced by it that I want to carry a gun over things like that. Yes, I would have risked getting in my car, and yes I think there'd be enough time if the door was already open (why wouldn't it be if I was putting stuff in it?) and I was right next to it (why wouldn't I be if I were putting stuff into it? Unless the scenario is that he was really leaving his car after putting stuff in it). And once in the car I don't see the argument that leaving would mean running the guy over.
