There are no traffic problems at 2AM which is when HHN lets out.
As for Annual Passes there tons of them sold for the other parks in Orlando, they offer the locals generous more practical benefits at the parks and Citywalk, on merchandise as well as food, and hotels. I'm not saying that Disney's pass doesn't have plenty of discounts, it's just that they're not practical to people that don't have any reason to stay at the hotels, and there are virtually no discounts on merch in the parks themselves plus Disney is out of the way for most locals who just want togo out to eat or hang out for a couple of hours.
