It's an interesting idea but I'm not sure if I totally agree with him or not. Well I do think we will continue to see motorcycles and scooters growing in popularity I'm not so sure if Wal-Mart would be best suited to the task. Different states have different regulations and even if Wally-world did start selling low priced scoots I feel they would probably push the 49cc models.
And I've written before how I feel they are under powered for most riding, even in the urban environment. Still though, interesting reading and worth your time and effort.
