I understand when I get my leaf, I am going to be able to optionally register my charger (being installed today) as a site which shows up on their computer map (in the car ?). That raises a curious question. Will others be able to see this in their car ? How is does community charger/sharing work ? my gut feel is that i would be happy to provide some reasonable use of my charger to travelers if there is reasonable (and honest) intentions. Any feedback on how this has been working in practice ?
