I wonder how much electricity they use annually just to charge the scooty puff? I suppose it depends on how far they travel. Do you think that anyone of them would have a solar charger on it to charge while they drive? Use a big solar panel as a canopy. I bet I could design and build one, could make millions!  Another thought. With flexible solar panels could we make wearable solar panels? We could turn every beetus barge into a power plant!
