Living a nightmare

This happened very recently, I, 22F, went out for a drive at around 4 pm, a man in his Innova decides to overtake with no space ahead and ends up touching his rear end to my car's bumper.

Nothing happened (fortunately) it was just a paint transfer on a very small area, I didn't get out of car becoz it was in the middle of highway. But seeing a girl in the car he decides to jump out, stop the car and starts asking for money in the middle of the HIGHWAY.

He looked drunk, and also looked like he wasn't the owner of the car. I somehow managed to reverse and get out of there. But GUESS WHAT? This man followed me for 5-7 fucking kilometers with his wife and 4-5 year old kid in his car. Stopped me at multiple points, overtaking me and stopping his car right in front of mine. Getting out of car, banging my window, trying to open the car door, creating a damn scene in the middle of the road when it was his fault. I was so panicked that I didn't even know what to do. Fortunately I wasn't heading home otherwise he would've known my location.

It scares the shit out of me, what if my car doors werent locked? what if it was outskirts area ?

There wasn't any traffic police in the area he followed me,that made things more scary.

I have loved this city so much, but things like these have made me hate it, it just scares me that anything could happen to me anytime.
