If you move to the seats next to the end doors, you'll be the first person that emotionally disturbed people and panhandlers see when they move from car to car injuring your legs with the door.
Inclement Weather
If it is cold out, the heat lamps will be broken or the crowd will not let you near them since they were there first.
If it's hot out and the heat lamps are inexplicably working, the crowd won't let you escape them since they were there first.
If the heat lamps aren't on and you try to turn them on, you'll activate a loud message that says "customer needs assistance on platform one." No one will come to assist the customer of course--good to know in a real emergency--but everyone will look at you.
If the heat or air conditioning in your car are not working so you switch cars, there will be fragrant or ominous emotionally disturbed people in the "good car" along with everyone else--who had your idea.
