"Do you have a car?"
This one typically comes from people who live in New York. Having a car in New York City is a luxury (and probably a huge pain in the ass!). But in Jersey, yes, most of us have cars. Do you expect us to walk down the highway? Unless you live in places like Jersey City or Hoboken, you’ll need one.
This is a kind(ish) way of saying "Ugh…" without having to actually do it. You’re basically still showing that you disapprove, but you're slightly too nice to really go for it.
"What's up with those 'exit' bumper stickers?"
So, there's this thing called the Garden State Parkway. It's a long highway that stretches through much of the state. People from towns near it like to buy bumper stickers for their cars that read certain exit numbers (example: Exit 117). This way they never have to face the ever-so-famous NJ question, "What exit are you?" from other residents (which is honestly just a way of asking someone where they live so that you can [silently] judge them later).
