Dynamic braking is an easy thing to do with electric motors and is easily installable on electric rover wheels. Rather than have rovers accelerate downslope to dangerous speeds, a tech node could allow dynamic braking to exist on wheels. This would prevent the coasting of rovers downslope to hi speed and charge batteries while providing a system of speed governing.
The tech is already very old and exists.
I do not suggest adding this to airplane landing gear until we see systems arrive IRL commercial or military craft.
A tweakable in the part UI could set surface set maximum surface speed to run rover wheel motors and minimum speed to run rover wheels as generators.
