I think people tend to be 'right-legged' as much as right handed. Improving comfort and minimizing fatigue are smart and prudent selling points. Deere really does have strong ergonomics considerations to their designs--probably the leader in that perspective. Familiarity and routine make anything different potentially uncomfortable once you're used to something different. I go for the clutch in my automatic and reach for the crank with my power windows if I go a while not using the car/truck. Habits are hard to change.
