Idk... for me it just made me even more curious about hitchiking in the US... Like, he makes it look easy to hitch with a gun (I didnt watch the whole thing, did he say how long it took him?), so I'm curious to compare the US with Asia...
People there apparently aren't too bothered about an armed stranger getting into their car.
It's not a bad idea to carry something for self-defense but if you've got a gun visible on your body and the first thing you're asking drivers is "Do you mind picking up a guy with gun?" you're bound to freak some people out and make them not want to stop for other hitchhikers in the future.
