Some one in their own world oblivious to those around them. Self-absorbed and unaware of the situation.
A dumbass. A clueless dolt.
These hackleheads on the highway need to put the freaking phone down, pick a lane and pay attention.

It's a hacklehead world. I just live in it and try to stay out of their way.
