Verify skidding/friction

[mikepurvis]

There needs to be some more rigorous comparisons made between simulated and real Grizzly, in order to verify the dynamic parameters.

Agreed. Also on the Husky. They are overestimated currently. Even if its not a straight numerical comparison (aka system identification) just to scale it back to match basic driving experience would be worth it.

There's also a certain degree in uncertainty wrt. if Gazebo handles such
calculations properly. There's no proper tire model, just a friction model.
