Considering how stupid most of them are, yes. I'd wipe humanity if I could.
Black => Walls
Red => Subway Exit
Green => Subway Entrance
Purple => People going for the exit
Blue => The way some retarded bitch decided to take
Really now, how fucking stupid do you have to be to fucking have a clear way from the entrance to the ticket entry gates and just go in the middle of everyone trying to leave, get to the wall on the right and then go through everyone AGAIN to get to the fucking gates.
Shooting her there and then would probably save humanity as a whole a few years.
It's easy as fuck. Cars drive with the right side close to the road in our country. That means that the subway, tram, bus, sidewalk, mall entrance, schools, markets, etc. are designed with that in mind.
When you walk on the sidewalk, for the most part you want to follow the rule as well. This prevent people bumping into each other whenever there's a corner.
That also means that you will enter/exit a building/subway/etc in such a way that you will not bump into the people trying to exit/enter.
It's rather efficient and would prevent a lot of unwanted shit.
The same with people not staying to the god damn fucking side of a door. How hard is it? You let people get out, you don't block their way and then you get in. You miss it? Well shit, your fault. You should take into account missing public transit at least once and leave early.
But nope, people just stay like fucking donkeys in the middle of doors and make it hard/slower for people to get out and in turn it makes it harder for them to get in... and ultimately they miss the buss because they were so stupid that they believed staying in the middle would make them get on faster.
Simple bullet to the head the first few hundred times and there, you have people that behave.
