Racial Incident and Harassment at Costco. What should I do?

My wife and I had an encounter with an aggressive driver who honked at us like crazy from behind while we were waiting for someone to load their products into their car and leave. After we parked, he waited for us to get out of our car and confronted us and called us “morons and a Chinese piece of shit”. I’m not even Chinese. I thought that would be the end of it but as we were shopping, we saw him again and he said “it’s the little Chinese man again” and I started recording as did he. You can see the video below but he accused me of stealing intellectual property and not being from this country. I was born and raised here. I have a PhD degree and I’ve been working so hard my entire life. How come this entitled dude accused me of stealing American intellectual property? I talked with the Costco managers then that individual dumped his cart and left. I’m extremely offended and still can’t take it out of my mind just yet. I’m going to submit a complaint to Costco customer service. Anything else that I should do, like filing a police report or what? I think that people don’t take racism against Asians really seriously.

Edit: Guys, thank you so much for all the support. There have been some wrong accusations that I was blocking the traffic. It’s disturbing so I think I need to clarify it here. I have downloaded the Dashcam videos that show the entire situation and I’m sure I was not at fault. I was not in the middle lane and that guy was the only car that pulled to that area. He chose to stay behind me and kept honking at me during that 2 minutes from when he turned to that parking to when I got to the parking spot. I can send the videos to Costco once they reach back out. If you guys have ever been to that Costco or any Costco, you know that it’s a 2 way lane and how hard it is to find an empty spot at the Costco on Research. So, don’t ask me to keep driving around for 15 minutes to find an empty spot when I literally waited for 2 minutes to pull in. I hope Costco mod can lock this post. I don’t want to keep explaining. Enough escalations here. Thanks again guys!
