How can you say any F1 driver is unmotivated? They are among the elite competitive drivers in the world. In that job it's perform or lose your seat. Each position means big cash to the team and the driver.
Trulli was motivated, so was Glock. Hamilton passed a slower car in the wet on the wrong tires. Just take your NSX out on a track with slicks on it in the rain and see how fast you are. Trust me, civics with rain tires will pass you.
