Hmmm. I watched the video and am not sure I believe Polaris. I like the way my Rzr handles but realize Polaris has some shotty engineering. Who makes a four wheel drive that can't stay locked and is crazy dangerous on downhill ice and snow -- Polaris. Heck we add doors anyway and I would not mind the support being further beside the seat. I also wear my seatbelt so don't care about that. As for the steering it's almost like a car now so I'm not sure what they mean.
Might be a good idea so trails can stay open. I don't see any of these items slowing me down.
