Well, also its different states
I remember the Heyer case and the accused pretending he was fearful for his life... despite not many protesters being around. And how much of a run up he got before plowing into them. Those laws are meant to make that legal. Just say 'I'm scared' despite the circumstances and you get a free murder
The idea is that I guess the car is like a gun so even if you're not driving at someone right now you could in theory do so in the future, same with how you can be armed without aiming at somebody right this second, because you can aim at someone the next second. Thing is you can't ask someone to drop the car in the same way you'd ask em to drop the gun, so they are using logic that basically means if you don't instantly obey while inside the car you are seen as not dropping your gun when ordered and are armed and dangerous.
The thing with the protesters is mainly something that applies to when they're out in the middle of the road, it doesn't apply if they're in the sidewalks, so it's kinda different. They can threaten you all they want and even attempt to break in the car but if they do so from the sidewalk it's allowed and you don't get protection if you ram at them on purpose on the sidewalks. It's more aimed at protecting people who like the guy shot in this story want to get away from violence.
