I Pulled Out Of A Parking Lot Too Fast And Got Followed And Pressed

Location: CO I was at my local dollar general and this guy with a boat had parked next to me his car was facing my car he was parked perpendicular to me and we both get out around the same time. This guy had his teenage son his gf and fiancé with him and I supposedly had almost hit the mom almost is the key word I had made sure they where all out of my way and pulled out kinda fast but not reckless and no one was hurt. I had heard shouting but did not think much of it and might have felt something punch/tap my car on the way out. The gym I workout at was right next to it so I pull in for my lift and this guy had pulled up blocking me in my parking spot and full fist banged on my window. For reference I am 17 and I had rolled down my window just a crack and he was yelling at me him and the teenage son saying “if you ever do that shit again I swear to god… I don’t care who your family is don’t ever pull out that fast again.” And was soft threatening me and I had felt fearful of it. I had apologized saying I had no idea I was that close and I promised to not pull out again but I am worried knowing the family’s history they will track me down they want me to go over and apologize to the girl and made it sound like I had too. I understand my part but in court they could give me a reckless driving ticket but is the threats reasonable and legally justified and is it possible if they continue to harass me to go to the sheriffs department. Any sort of advice is needed!
