The GoPro hero7 onward cameras have a version of image stabilisation in some resolutions called HyperSmooth.
I was tempted to change the resolution/frame rate so i could get normal stabilisation without the hypersmooth but i think it looks pretty good on that video
I competed in a two day hillclimb event this weekend, with gravel on the saturday and tarmac on the sunday.
Here's my fastest run on the gravel, Haven't had chance to get the tarmac in car off the gopro yet
