Let me just add that the Spa'66 may be a little bumpy, the bigger problem is that there are some mesh holes in several places at the edges of the track where you would put your outside wheel to get a better angle for the oncoming apex. The whole wheel or both front and rear would fall into it and you'd probably lose the car.
I've found 3 places which ender or almost ended races
1. Raidillon to Kemmel section on the left edge of the track - sections from 2 to 3 on the map image
2. La Carriere - right side of the track preparing for left kink before the right kink at the "Grandma's house"
- section 10 on the map image
3. After the house, the next right kink - left side of the track has a hole just as you'd want to get a better angle and turn right into that kink - section just before 12 on the map image
It's not a big deal in the end, at least not for this track because the physical road mesh is it's own kn5 file. Sergio does it with his tracks. He provides alternate road mesh kn5 files that can be swapped around for those that want a smoother ride or a bumpier ride. First I need to learn how to adjust the physical road mesh.
