True, but Inter-vehicle could be cool for several things. First is the EV equivalent of jump-start-and-bring-a-can-of-gasoline, an in-the-field recharge for cars that run out before the recharging station or home charger. It would also be useful as a plug for a range-extending spare battery pack on a small trailer. Seems like other potential uses too.

(But no, I'm not liking that Tesla is taking the typical entitled-ass attitude of avoiding all the standards bodies, doing whatever they want, and expecting others to ratify their standard. If it is that good, it should be readily agreed to by the relevant standards bodies.)
