Wow, that same thing happened to me once! But when I froggered across a busy street to come to his aid and ask how I could help, he was grunting and mean and tried to slap me.
Ever after I would always see "pedestrians" near my car cruising in motorized wheelchairs. Such an astonishing coincidence.
That's ridiculous.. although I can understand. Being helpless off the side of a busy street can be very embarassing, and some people aren't nice to begin with. Stick a cantankerous person in a wheel chair, then tip him onto the sidewalk...
Yes, it is quite a coincidence. Just last week I saw a motorized wheelchair crossing the street and was wondering how much of a risk a person in one those was taking when they went out on their own.
