There a lot of numbers higher than the 9Gs that are safe-ish and reasonable-ish for human drivers/pilots to experience regularly. A big bag of water with bones inside that likes to breathe doesn’t take well to high levels of acceleration, eg. really fast turns.
Outside of planes, I don’t know that any land or water based vehicle could pull 9Gs as you’re limited by the traction of the tires and whatever physics effect boats on the water.
F1 maxes out around 6/7Gs, but they’re not solely limited by tire friction, they’re effectively upside down planes that use their airfoils to get more traction. A lot of the difference is sideways Gs are harder. A pilot getting pushed down into their seat while banking through a turn can have more control than a driver getting pulled to the outside of the turn.
