Songs for the carpool lane

Speedtalking math-vlogger Vi Hart isn't just a math wizard: she's also a brilliant songstress.

She's collected a few of her "carpool lane" songs, which she invariably sings when she's blessed with access to the HOV. Below are her original and rocked-out version, and there's more on her site (including a hymn to progress bars!).
