Good escalator etiquette is actually bad for the machines themselves and the commuters who use them. Anyone who rides escalators regularly knows there are some unspoken rules about using them. People who want to stand and ride the revolving stairs should stay on the right-hand side to keep the left side clear for anyone who wants to walk up the escalator. But it turns out, this method is actually unsafe and inefficient.
