What is your biggest pet peeve about driving and why?

Mine is people who wave me on when they have total right-of-way. My dad told me when teaching me to drive to never go when it is not my turn, even if they wave me on, because you never know who may be looking for an excuse to cause an accident without making it appear to be their fault – presumably to cash in by suing you. Also, it wastes time when they wave me on, I gesture no, they insist, I insist. Just follow the rules! They make things run smoothly.
