Lady circles Starbucks to scream obscenities

This morning I pulled into a parking lot and was in the main aisle/roadway. A driver in a large SUV could see me and several cars behind me approaching but decided to lurch into traffic, obstructing my right of way. She wasn't too far into the road and it happened quickly, so I veered around her and kept moving. She had completely cut off the driver behind me, who slammed on their breaks to let her go, and then proceeded to follow me through the parking lot to the Starbucks drive thru line.

I assumed she was heading that way too until she pulled over outside the line next to me, honked, and rolled down her window to coax me into an altercation. I chuckled and minded my own business and she eventually drove off. A few minutes later when it was my turn to order, I rolled down my window and was greeted by aggressive honking and heckling from the lot. "Not afraid to roll down your window now, huh?!" This driver had circled the Starbucks and waited several minutes for an opportunity to harrass me again. Truly unhinged behavior! I was prepared to call the police at that point, should she have followed me again or parked by me in the lot.

Her driving and attitude go hand in hand I suppose, equally entitled and aggressive.
