Beautiful presentation. I love when visualizations serve the goal and not the other way around. Tufte would be proud.

My kid (6) crashes all the time, and she is naturally attracted to picking Peach. I'd say because of that, a character with high acceleration is going to be better. Though she also just likes to push the gas.
Though we're playing the one from GBA on Analogue Pocket. Which is probably a lot less advanced as the one in question here (a game for Wii U from 2012), it does resemble Wacky Wheels quite a lot.
Tufte is still alive!
