I don't think I could get rid of my mobility scooter - there is no where to put any shopping here, or stow a walking stick. Would it go up a kerb? I doubt it. I think this might be good for indoors, shopping malls, or even airports, but wouldn't be practical for me.
I'm not even sure if I would be comfortable with my feet so far back, and it looked as if the model's shoes would get scuffed too.
