So, this isn't mainly for disabled people, I take it?
I mean, it looked like a wheelchair to me, but hey it's the 21st century, sometimes it feels like all bets are off. :/
But I do not consider myself qualified on this topic, as I have no idea how far the obesity problem has gone in the US.
EDIT nevermind, I'm being stupid here. Too much coffee probably. Commenters below are right.
People choose immediate gratification over long-term solutions all the time.
I'm also thinking the general public wouldn't be interested in something that makes them look disabled.
this is pretty awesome for someone who is disabled/old/obese and the idea that you use the core muscles would be great for obese users who can't walk or ride a bike.
