I've never thought it was.
One thing that always stuck with me when I traveled was talking with other business travelers who'd complain about driving in C-Bus. Most people complain about driving in big cities like NYC, LA, and Boston, but C-Bus can really be a nightmare if you didn't grow up there and learn the layout like the back of your hand. You won't find many other major cities that permit a five-lane change over 1/4 of a mile to get from an on ramp to an off ramp. The 70/71/315 split is a disaster if you've never driven it before.
