Born and raised Long Islander here. As soon as I saw the title of this thread, I knew it was one of the parkways.
The parkways have low bridges, tighter-radius turns, sometimes ridiculously short or even none-existent entrance/acceleration lanes, and sometimes sharp/short exit ramps that end with a stop sign about 100 feet off the road.
Everyone on the Island knows about them, a lot of folks avoid them altogether, and any professional driver should be aware of them as well, and if they aren't, I'd call that negligence.
ETA: Here's an example. Note the "generous" acceleration lanes. ;)
