My personal experience with them doing off road is that they are a PITA. The reason is that they are built into the steering wheel, not the steering column. So as you turn the wheel they move. Since you are watching the road/trail/rocks/trees you don't know where the paddle you need is when you need it. And, unlike on F1 race tracks, it is common when off road for the wheel to go through 1 or 2 rotations doing a tight turn. Finally, I prefer to reset my hands to the 9/3 o'clock or, in heavier stuff, the 10/2 position. But that can be nowhere near the paddle I need. Had they built them into the steering column so they were always in the 9/3 position that would work for me - right hand to shift up, left hand to shift down. But they are rarely there.
