Everytime I see one of these, it really ticks me off that drivers are that impatient that they are willing to be risky and put their and other people's lives at risk to save maybe 3 minutes on their morning commute. Really just ticks me off. If you're wanting to go fast then get out on a deserted road somewhere or maybe build your own track, but don't do this stuff on a busy road with thousands of cars around you.
