What bugs the hell out of me are drivers who slow to about 2 miles per hour for dips in the road. You're not carrying nitroglycerin in that thing, for Christ's sake.Car was driving less than 20 down a main street. Got to the point where multiple cars behind it all caught up to it and formed a line. Was the person looking for an address? A parking spot? Apparently neither because this went on for quite a distance. Then the person finally speeds up, but only for a few seconds. Then starts driving slowly again! Was this person on the phone? Was an old person driving?
