What's the absolute worst Mario Kart experience you've ever had?

For me it's when my Mom forced me to play Mario Kart with my 5 year old cousin. I was playing alone when he was over and my Mom said no video games or he could play too.

I let him play and turned on auto accel and smart steering for him. I let him choose his character and we were racing.

For no reason he got angry when he saw another player and screamed in my face saying "I don't like them!!! Get them out!!!"

My mom, (not knowing anything about Mario kart) said, "well, take the other guys away"

I said I couldn't and she said "That's it, go play outside with you little cousin"

He screamed again saying "I WANT TO PLAY THE VIDEO GAME THOUGH"

My mom said, "fine, he can play on your gaming device while you go do something else"

I went to my room upset and angry and covered my ears because all I heard was screaming.

Before you know it he threw my joy cons against the wall and broke them. Worst day ever.

Holy spoiled brat. Tell him i said hi lmao.
Anyways, my 6 year old cousin was playing Mario Kart World together and we used single joy-cons, and I decided to do single player on the tv with my pro controller. little did i know, my cousin lost the joy-con SOMEHOW and blamed it on ME!!! since she's younger than me, the littler, the more easy to get what they want.
that's why my other 5 year old cousin that hasn't even discovered electronics yet is my favorite.

when my dad who had only played the game 4 times beat me

mario kart 7 on a Dell OptiPlex from around 2011 (it couldn't even support the opengl renderer. 3fps in menus with software)
It had such "good" "audio"
