Frankly, this invention won't last long and for various reasons:
1) It won't replace cars as it can't go far, it can't protect you from bad weather and it can't take anymore luggage than what the owner can carry on his back.
2) It won't replace bikes as these already exist and are satisfying to those who use them (I do).
3) They can't be stored in a very small place like next to the garbbage bag near your legs when you sit in an office.
UNLESS, of course, it's meant for people who are too lazy to use their muscles like bike riders do or even to go by foot (as the distance is short anyway).
It's just....a gadget for Xmas
