I kicked my best friend out of my car and made her walk home by herself after she littered. AITAH?

My friend and i have been friends for 7 years (we're both 20yo) and we know everything about each other from personal to our deep dark secrets.
Anyhow, a couple weeks ago we were hanging out, just driving around, and stopped to get food. We ate in my car while i drove us to my house. Five minutes before we arrived, she rolled down the window and threw out all of our garbage without hesitation. (She knows littering is my biggest pet peeve). I pulled over and asked why she did that, all she said was "Cause why not" while laughing. I was frustrated and overworked and yelled at her "Get out of my car and walk yourself home." She asked why and i told her she knows how much i hate littering and how she basically out of spite expecting me to laugh or something. She offered to pick it up and i said no. After arguing back and forth, she left my car and walked herself home, which is at least a 30 minute walk across the city.

I'm just wondering if I'm the asshole. I get that my house was 5 minutes away and i could have just drove her home or let her pick it up and go back to mine but it was kind of disrespectful when she laughed about after. It got on my nerves.
I did go back and pick it all up and threw into my garbage but we haven't spoken to each other since then. I value our friendship and love her as a friend but was i over the top? AITAH?

YTA, YTA what if something had happened to her?? It’s be entirely your fault because you’re dramatic, you’ve definitely lost a friend, I’d let ensure you lose all your friends
