Looking for some advice:

I am relatively new to the area and am having a weird issue. The other morning while sitting in my car by the gym, this dude pulls up to me in a Mustang and starts yelling at my car window. At first I thought he was asking for directions so I roll my window down

Him: “You got something to fucking say?!” Me: “im sorry? I think you have the wrong person” Him: “dont play that shit bro I know you know me”

Then he whips his car around and goes to block me in then sits in his car behind me waiting. I got so spooked I drove off.

Anyways two days later I feel safe enough to try to go to the gym, and the dude (who it turns out works at a construction site down the street) walks past my car again and yells something at me before walking on.

I have no clue who he is and he must think Im somebody else and it just feels shitty to feel threatened for just trying to exercise before going to work. Im also nervous during every workout that im going to come back out to a fucked up car, but I know that guy will be there every morning at the same time as me. Any advice?
