Last week, New York’s MTA announced it would be launching a public transit etiquette campaign. The focus of the campaign will be on people who take up space by wearing big backpacks or sitting with their legs splayed unnecessarily wide (aka “man spreading”).

That got us thinking … which rules need to be reinforced on BART and MUNI? Anyone who rides public transit regularly knows that the unspoken rules of society go out the window on BART. It’s the wild west out there.

Here are a few of our big beefs, for starters. Let us know your commuter pet peeves in the comments:

Don’t put your things on the seat next to you so that no one else can sit there: You revoked part of your right to private space when you willingly got on PUBLIC transit.

No loud music: I’m sorry you forgot your headphones, but you can’t put your iPhone on blast and share your tunes with everyone else on the train. If your beats are disrupting my quiet time with the Serial podcast, your music is too loud. On that note…

Don’t have loud phone conversations: No one wants to hear about your weird foot thing or what Gina did at work today. Save it for when you get home.

Take a break from work and don’t balance your 15-inch MacBook Pro, wifi hotspot and wireless mouse on your lap: Everyone’s seen that guy (or girl) who is attempting to transform BART into their personal office space. Give your weary eyes a rest and disconnect for a few minutes. We all benefit — especially the person next to you who keeps having to pick up your dropped hotspot.

Take off your giant backpack: And please hold your big purse in your hand, not on your shoulder. It’s crowded enough on BART and MUNI as it is.

Don’t use the close proximity as a cover to creepily touch other passengers: This should go without saying … but apparently it needs to be said. I have a friend whose hair was stroked repeatedly by a stranger on BART. I’ve had my legs grabbed while standing by seated passengers. You’re not that sneaky. I guarantee the other person knows what you’re doing — and it’s not OK.
