Wait, Bowser and Wario are the fastest? I thought it was the other way around. I guess it's reversed from Mario Kart 64.
But they seem to have ignored kart physics and made it more like a car, where bigger cars might accelerate slower but can accommodate a more powerful engine.
I hadn’t actually thought about it before but as an incredibly skinny person what you said lines up with my experience in a kart. I could seemingly go slightly faster than others but more easily span off and lost control.
When I wrote that comment I was thinking one might tune the kart for the driver to make up for lack of acceleration which would reduce top speed.
