Obliviosity

I've been making some observations lately.  It seems that more and more I am finding instances of a new condition.  I'm not sure if it's a virus, syndrome or disease, but this condition causes people to be completely unaware and unresponsive to their environment.  They operate as if they live in their own little worlds, navigating as though their actions and behaviors have no impact on any one else.  I call this condition obliviosity.

Examples of this condition include:

• The lady driving her car who decides to take a left turn from the right lane by way of cutting across two lanes and almost getting smashed by the city bus (traveling in the left lane and clearly planning on going straight).

• The guy who takes two steps off the escalator only to come to a complete halt, to check his phone.

• The snowboarders who sit in a line across the top of the trail to strap in thereby creating an obstacle course for anyone who'd like to actually go down the trail.

• The able-bodied people who choose to sit in the handicapped spots on BART immersed in their {book|phone|kindle|iPod} failing to notice much less move when someone who deserves the seat enters the train.

• And, of course, the woman at the grocery store who parks her cart in the middle of the aisle, completely blocking your ability to get by.  She is likely chatting on her phone, comparing prices and/or distracted by her kids.  (Based on this observation, I think I might be infected too!)

Have you seen this condition lately?  Is it on the rise?  Do you think it's a virus, syndrome or disease?  Is there any cure?
