i change my driving styles depending on whether or not people are in the car with me or if i'm carrying something that doesnt like being jerked around (i.e., josh's couches, josh/john's mattresses, things like that). There's a damn good reason the tires on my truck are pretty bald. When i put the winter tires on, these summer tires are going in the trash.
Even when I'm driving by myself theres things I don't do that I can do in GT. the street isn't a track after all, despite all of my attempts to drive like I am on a track :)
