Parking police Karen situation got physical altercation

This morning, I had an encounter with a Karen of a neighbor who believes the parking spot in front of her house belongs to her. I parked there overnight, and when I got in my car this morning , she approached my window, shouting and threatening to call the police as usual. I asked her to kindly stop salivating on my car, but then she goes in and gets her son who came over and instantly opens my driver’s side door (I thought central locking was on), grabs me, trying to pull me out.

For context I’m 6'2" 75kg, gym regularly and train Muay Thai, he’s about 5'7" and chubby with a beer belly. I got out of the car and pushed him away, he slams into his mums parked car across this narrow road. But he kept coming back. I managed to push him away multiple times but at one point he grabs my jacket and I couldn't get free, so I took a small step back and kneed him in the stomach/side. Neighbors came out to intervene, and I just got in my car and left pretty pissed off.

I didn’t want to stay longer and possibly seriously hurt this guy. One of my other neighbours has reassured me he’s seen the whole situation which I’m relieved about Incase Karen actually calls the police and twists the story. I’m not looking to report it as honestly I don’t feel threatened by this guy and I have 999 other things to do. I double police would even do much anyway. Just keep wary everyone and avoid these kind of situations at all costs as it could’ve ended horribly for either of us. All over a public parking space.

UPDATE: Reported him, police said thank you and that they’ll keep tabs on the situation.
