Oh yeah I'm sure they've made accommodations to make parking not suck in the area, but driving around Brooklyn is pretty hideous under normal circumstances let alone when there's an event going on. The thing is, Islanders fans have long enjoyed the convenience of driving to Nassau Coliseum. It's an easy access venue, there's a Marriott across the parking lot for after game drinks.
That said, yes it would be completely moronic to change the name on account of Brooklyn is geographically part of Long Island. The people making a big deal about it are from the city and they adamantly refuse to accept the geographical reality. You tell someone from Brooklyn or Queens that they're Long Islanders and they will absolutely jump down your throat.
