granny driver
The little old blue haired lady who drives a car way to big for her.She cannot see over the steering wheel.She drives around with her right turn signal on constantly.The rear view mirror is useless because it is cocked into a make-up mirror position for applying lipstick.Usually has the back seat full of poodles or other useless dogs. Comes to a complete stop when making right hand turns for fear of flipping the car. Uses the horn instead of the brakes.
I'd rather follow a school bus at 3 o'clock than a granny driver.
