This happened yesterday. Not dangerously close, just aggravatingly close.

I was headed north on a 4 lane. Two southbound cars were waiting to turn left into a mid-block shopping entrance. 1st car goes a safe distance ahead of me. I keep my full steam going. 1st car has to slow for the bump at the entrance. 2nd car looks at the slowing car, looks me and my strobe cygolite in the eyes, then makes the turn.....stopping in the middle of my lane. I then had to make a quick stop to keep from smashing into her side. I put my hands up in aggravation. 20'ish girl looks at me with half her gum in her mouth, half her gum wrapped around her finger (im not kidding) and mouths to me "whatever". The look of discontent in her eyes told me full well that she knew exactly what she was doing.

Some people honestly just don't care.
