What Car Brand Has The Worst Drivers?

There are a lot of bad drivers on the road. Which brands do they gravitate to more than others?

I have to say that I seem to get caught behind an inordinate amount of Mercurys. They're going slow in the left lane. They're cutting me off. They aren't signaling They drive five under the speed limit. They leave their high beams on when they're coming towards me. Maybe Mercurys hate Miatas?

Frankly, I kind of find Mercurys to be my own personal menace.

What car brand do you see on the road that is almost guaranteed to have a driver behind the wheel so bad that you'll be infuriated?
