Bug: Sometimes when the taxi stops, if it happens to be on a set of steps a certain way, it will start bouncing up and down in one spot like a jackhammer. Fares getting in or out of the taxi seem unaffected by this also.
Bug: Character Gus: When you select Gus from the drivers menu, he turns to the camera and says "Hey hey, let's have some fun!" The tail of his Hawaiian shirt passes through his hips and pants.
