well i can explain, or i can let you continue on being a dick...

i just re-read it, and yeah i didn't really explain that part well at all, i also didn't really put a that much effort into it either because as you sarcastically suggested I'm not an actual detective, I was tired... and well, i'm on reddit... i literally wrote that lying half-naked in my bed

put it this way, say your a guy walking along the side of the road in the middle of the night and you just did something bad, say you just stabbed your girlfriend and tossed her in a ditch somewhere, or you were high and for some reason there was a knife on you, or maybe your a lunatic and your just walking in the middle of the road in pitch black darkness for no reason other than you just had a lapse of sanity... whatever the reason is, you're not up to anything good and suddenly this happens

out of nowhere some guy in his pickup truck backs into you going... say 15 mph, maybe not 30 as I said before, whatever it was if you look at the video it was pretty fast, fast enough that the driver had to put the breaks on decently hard enough to stop before he hit him

so if I was that guy I'd be a little on edge, why did this back up so quickly toward me? did he see me doing whatever it was i was doing, is going to get out of his car with a flashlight and start asking me questions?

the point i'm trying to make here is that throughout the video the storm chaser is clearly in this high-adrenaline state, you can hear it in his voice throughout the video, his hard must be pumping twice as fast as normal, not a single thing comes out of his mouth that he isn't yelling,

picture the storm chaser isn't a storm chaser but instead he's actually a cop responding to a report of a guy with a knife in his hand walking along the side of the road, the same emotional state that the storm chaser is in is the same emotional state a cop would be if he was about to confront an armed pedestrian, high adrenaline, his eyes are probably bulging out of his head, maybe some sweat is starting beading on his forehead

now picture how the guy might feel in this moment, a pick up truck backs up into him out of nowhere, nearly runs him over (yes, it's a pick up truck, not a cop car) and he starts yelling "Are you okay? Are you okay?"

Yes it's not what a cop would actually say which is "Put your hands in the air where I can see them." but it doesn't matter what's coming out of his mouth because the guy is probably already so paranoid about the some guy randomly backing up into him out of nowhere that anything that comes out of the storm chasers mouth, so long as it's him yelling is likely to make him feel like he's in some sort of trouble, it's called "state transference", if you don't know what that is, it's basically a phenomenon that occurs between two people having a conversation where one person could be talking to other in japanese about, say, this exciting road trip he just took and the other person could have no idea what he's saying but that person will nevertheless be emotionally drawn into the story through the person's body language and the tone of his voice, when the japanese guy is at a point in the story when something exciting happens, the person despite not knowing what he's saying will feel excited a long with him

so my assumption here is that the guy isn't reacting to what the storm chaser is saying, but feeling of panic behind it

which is why he eventually says is "I want my attorney" and later "this is bullshit, dude" as if he's still convinced the guy is a cop after he tries to murder him out of desperation of being caught

so anyways, long story short--- this is all 100% speculation and the guy just might be bat shit crazy, who knows, but that's what i took from it
