Voltaire said "The perfect is the enemy of the good."
Shakespeare said "Striving to better, oft we mar what's well."
I think this sport is full of good, well meaning people who can't help but ignore ancient wisdom.
Auto-steer removes part of the human element of a sport that's already seen as cold, individualist, and robotic. Good driving is a skill unto itself, and for me, personally, I enjoy driving EVERY BIT as much as skiing, sometimes even more. If I'm just going to be a passenger to the robo-driver, count me out.
I have zero fault with people trying to solve unique problems, but at some point, don't we all inevitably just become cable skiers?
