Discription of Events: I was pulling up to a McDonalds drive thru (1831 w Burnside st Portland OR), there were 2 entry ways, I came in one way and the other guy came in the other, there was a line so we both had to wait. When the car in front of us pulled forward, I waited for the other driver who was waiting to pull up, he didnt move so I waved at him thinking he was letting me pass, but the second my car started to move he slammed on the gas and almost smashed into my Lexus RX, tires screeching and everything. When I honked at him he then proceeded to get put of his car and approach mine calling me all sorts of profanities and threatening me. He told me to get out of the car (while I have my 5 year old son in the backseat) so I locked the doors and continued to honk at him to hopefully get him away from my car. He than finally went back in his car and started screaming at me from there, and then got out of his car 2 more times before an employee came out yelling for this guy to stop. I talked to management there, and they have cameras all over the parking lot and I can see it got the whole thing recorded. This happend on 04/14/22 at around 7pm. He terrified my son and caused a whole lot of unnecessary stress and reckless driving
