Gas makes a car go

I know that NASCAR isn't everybody's cup of tea, but today's race at Pocono was both exciting and hilarious.  Brad Kesolowski ran over his pit crew, Kevin Harvick exploded his engine, and Kasey Kahne hit a pit road wall, sending helmets flying into the air.  In the final three laps, the top drivers ran out of gas - one by one - leaving the field open for Matt Kenseth and his slightly-better fuel-saving strategy.
