yeah, I'm still waiting for video of putting it into a car. And some of these more recent videos look like they took their prototype to a convention or some sort of show-and-tell, and then let a bunch of people try it out. Here's another one.

I would really like to know how heavy it is. I have a minivan with a ramp, so I bet if I had one, I'd probably be able to get it into my car, as long as the wheel base isn't too wide to go up the ramp.
