Geez that's crazy. That's why I have a general aversion to public transportation. I could never make myself take the bus to class when I was in college. With public transit, if you're delayed/broken down its 100% outside your control and you can do nothing to change it.
With your own vehicle you can try to find another way around a traffic jam, say screw it and drive to the nearest bar, or cobble together some roadside fix if your sh*t breaks.
