That's why I thought Fitt's Law applies well to the recent runaway Toyotas (I talk about it here: http://www.rioleo.org/the-prius-syndrome.php). Braking and accelerating are two opposite tasks, and yet they are so close to each other that driver error, though rare, may actually be explained. Oh and by the way, the Gmail Undo feature has been a lifesaver for so many occasions!
