A question to those more experienced than me.

When driving up bumpy & rutted hills I sometimes find that the throttle is ‘surging’ because of my foot bouncing a little on the accelerator pedal. I know some folk with narrower cars wedge their knee against the door to keep things more steady, but the Patrol is a bit too wide to do that (at least for me). Seems to be more of an issue when revs are a above about 2500rpm. What do you do?
