Atlatl Vehicle Defense System, field testing

I needed to pick up some whiteboard markers and drove to Staples to get them.  In the parking lot, a fellow careening across the parking lot was stopped by me two by my proper driving as he cut across lanes to park.  The final straw was in me taking a pull through that blocked him from having the parking spot for which he was gunning.  He circled around and back to get an available spot and glared at me as I walked past.  I was worried about him keying my car so I waited in the store vestibule until he passed my car.

He reached into his pocket and pulled out his keys approaching my car.  He stopped, looked at the 40 item bundle of atlatl darts on the top of my roof, put the keys back in his pocket and returned to walking towards the store.
