Yeah its bumpy all right, but thats part of the magic! Needs a curious balance of pure balls and aggression and a little bit of delicacy, dont really know how to describe it but it is some buzz when you get a good run up one of those hills! You've got to have a predicable car, nice and soft or else when you hit those bumps it can be a 30 foot drop onto the rocks or into a mountain thats been there for a couple of million years!
