Color Coding for Cars

It has occurred to me that many items are color coded and this makes it easier to quickly discern something about the item.  Labels on decaf coffee, for example, are usually green.  Warning signs are often in red.  What if we used color coding on cars to help us distinguish between types of drivers?  We could see, at a glance, what type of driver we're dealing with.  Here's how it might work:

red = fast driver; usually immature, impulsive; angry or irrational if crossed
blue = middle-aged driver; mature, experienced; generally cautious and law-abiding
green = new driver; immature, inexperienced; good reflexes, but tends to push the limits
yellow = youngish (but not green); happy, carefree; basically cautious, but sometimes inattentive when singing along with song
orange = prisoner; should not be on the road in any event
pink = young woman; usually attentive except when applying makeup or talking on a cell phone
purple = think former (or current) mental patient; erratic; alternately goes too fast and too slow; makes left turns from right turn lanes, etc.
gray or white = older driver; mature, experienced, but sometimes drives too slow
black = think drug dealer; sticks to big cities and interstate highways; a tad fast
