If you are:

• scared to drive the speed limit
• scared to drive 5mph over the speed limit
• scared to go around a 90^o corner faster than 5mph
• scared to pass someone faster than 1mph over their speed
• unaware that the left lane, in most cases, is a passing lane
• unaware that the little stick on your steering column is for signaling your intentions, not something that causes an electrical malfunction in your lights
• unwilling to use said stick
• unsure of the exact dimensions of your vehicle
• unsure of the exact abilities of your vehicle
• someone who believes 1' longer than the length of your vehicle is plenty of room for you to slide in
• someone who doesn't believe in checking your blind spot before coming over
• someone who doesn't look behind you when in reverse
• someone who pays more attention to your cellphone conversation than to the road
• in such a hurry to get out into traffic, but unwilling to do at least the speed limit
• prone to waiting until the very last second to get in the lane you need to be in, thereby slowing all other traffic to a halt

More to be added as it happens. Keep coming back, I seem to be adding things almost daily. Suggestions/additions welcome.  :)
