I tried to teach my young teen daughter to run the riding mower. She did run it - in pretty patterns around the lawn that didn’t cut all the grass. Also ran over a few ornamental bushes. I did it myself after that.
When my sister was a teenager and I was still too young, we had the old corded Black and Decker lawn mower. She hated it, and eventually ran over the cord on purpose. She only fessed up decades later.
