What is the most fun vehicle you ever driven/piloted/skippered?

* PAC Cresco 720 highly modified former cropduster - could take off and land on a dime - https://www.youtube.com/watch?v=1_MO5Wfomks

* OKA - seriously good off road traversal - https://www.youtube.com/watch?v=fwflmCkYO9Q

* Wabco Haulpak - every kid likes a giant Tonka truck and these paid for my room and board while I studied.

As far as seriously fun goes, I've got my fingers crossed I might one day get a chance to have a go at a local home built DIY ground effect boat|plane: https://www.youtube.com/watch?v=1ILbQHnHPnY https://news.ycombinator.com/item?id=37964608 - it's currently a bit dinged up.

Jetski was thrilling but kinda underwhelming, you can really only go back and forth, turning is too slow at speed to be interesting. At least that was my impression.

I drove a gas powered go kart once, it was more like an agile ATV. Had a roll cage. That was fun.

An underwater scooter. Basically a car battery, motor/propeller and two handles in a plastic case. Closest I've ever been to the kind of flying you experience in dreams.

Was my Porsche 911, now a Tesla model Y. By a country mile.
