There are a number of things that we look at with respect to holding the level of investigation—safety implication, age of vehicle, warning to the operator, if there is a warning, and also physical evidence. We do go out and look at these vehicles. So often we may have something where an operator indicates that the vehicle took off by itself, but physical evidence could suggest, and shows and supports, that at times there are driver errors. They're unfortunate errors, but they do take place, and even sudden acceleration reports from the past many years have shown that driver error is something you cannot overlook.
