I think it would be cool if monster trucks had more active suspension. Like if they could actively push and pull their tires, and could jump just using their suspension. I think it would open up a lot of tricks. Although I am not sure how the drivers would be able to independently control the motion of each tires suspension.
I searched around to see if I could find anybody doing something like this but couldn't find anything directly relevant. But I did find an article about some clever active suspension used in rally cars. https://www.roadandtrack.com/car-culture/a44069848/mclaren-proactive-chassis-control-citroen-wrc/
