The absolute worst thing that ticks me off everyday is people backing out of their driveway. Now let me explain. It's when you can see them plain as day waiting at the end of their driveway, and you both have a clear line of sight of each other. They wait a few seconds for you to get closer......then they back out onto the road (Speed limit is usually 80 kph around here)
Now sure you have to slow down and I don't mind doing that, but it seems like all people around here have a hard time finding the D in their automatic's once they are parked on the road in front of you with their reverse lights still on, making you slam on the brakes until they find the right gear. And once they make you come to almost a complete stop, they look up shocked in their rearview and pin it to get up to speed.
I kid you not on my trips into town this usually happens once a day! And its not the same people over and over again either...Must be something in the water....
