DC / Baltimore drivers are rude. Not NYC rude. That rudeness is expected and almost permissible...a natural byproduct of a concrete jungle with too many people, too little road, and too hurried lives. No, the selfish aggressive driving in this area is confounding to say the least. Parking spaces are wonderful displays of people's behavior. After searching relentlessly for a space and finding one - unoccupied or soon to be - another driver approaching the opposite direction should see the turn signal you recently engaged. Instead they attempt to claim your parking space. Had they seen it first? Doubtful. Plus, you called dibs. Sometimes a honk can shake them into reality but other times they still manage to claim your space. Perhaps it's the singular focus of securing the cherished parking prize that causes drivers to be blind to someone's blinker. But when dibs are called on a space, respect it!
