This is certainly cool tech, but I don't think they'll sell many of these.<p>I worked on advanced mobility products for over 15 years and with hundreds of quadriplegic folks in wheelchairs and listened to all of them.<p>Over those years I saw a lot of very cool products designed for them that they didn't want, need, or have any interest in using.<p>A wheelchair that goes off road is one of them. Most of those folks have no interest at all in that, and most will tell you, if you get to know them well enough, they're afraid of it.<p>There's good reasons for that too. We're talking about people that cannot pick up a sandwich or open a can of soda. They cannot lean back and forth much, or turn side to side. They don't have the muscle or muscle control to handle the shocks of bumps of going off pavement.<p>Now I have met some paraplegics that would love those. Not many, but a few. They were all "Type A" personalities who loved risky behaviors even after braking their backs.
