I don't know how they would fix it. It's inherent with the arena.
One of my gripes, and it only affects locals, is that the game day shuttles drop people off literally a mile from the arena. It's borderline undoable for us old people. Parking is grossly expensive, and the lines for the elevators at the parking garage after the game are ridiculous.
I have only done the shuttle once, and even though I didn't dally around after the game, I barely made the last shuttle back. I was the only passenger on the bus.
