Discription of Events: This driver was holding his hands out the window yelling at me after he passed me at a cross street, i was parked and was minding my business until he began making gun shooting signals with his hands at me yelling, i finally got behind him as my destination seemed to be near his, and he kept break checking me when i was far behind him- he seemed to be on heavy drugs. It was scary and i would like to keep other drivers safe
