Must the entity comprising car and driver try to avoid having a split personality?

A colleague, asking me how I like my new car (an Audi TT Coupe), reminds me that when I first got my New Beetle, I commented that I felt compelled to drive with extra consideration for others -- e.g., smiling and nodding at drivers who yield to me, obligingly changing lanes to allow other drivers plenty of room to merge into traffic. There was something about the overall image of the happy -- smiling -- car that required the driver to have a matching personality. It's always bad to be a selfish or angry driver, but any touch of these admittedly human qualities is really going to stand out if you're driving a Beetle. It's like getting into a fistfight while wearing a peace sign. After driving the Beetle for five and a half years, I'm now faced with the notion of merging with a different car's personality. It's quite a different sort of car. Is it me? Driving, do I form a single personality with my car? But it's not so obvious what the Audi TT personality is. It's a subtle process of self-discovery. What am I like as a driver of this car? What is the integrated Ann/Audi persona? If I can't discover it, Ann/Audi will be a split personality.
