Hi Dan
Yes, that road is certainly bumpier and actually turns into a dirt road at the end for a couple of miles.

The rotational effect you are noticing must be Gopro Hero 8's image stabilization algorithm. I do have it at the normal (on) value (not high or hyper). So perhaps that allows for some of that effect. But I am not using any special apparatus. Here is how/where the suction mount is set up on the hood/bonnet:

You got me thinking and the last time I owned a Gopro was probably the Hero 2 many many years ago and recorded some videos with the camera mounted inside the vehicle to the windshield. I just watched one of those videos again and it also did not look too bad, even though it did not have hyper smooth or any kind of image stabilization then:
