I drove 1800 miles in a Hydrogen Car

Seems like a less efficient method to power EV mostly just for a quicker "recharge".   If recharge speed is that critical, let's just standardize EV batteries and make it externally accessible so you can have robots at battery stations replace a depleted battery with a full one in under a minute.  If not, then aside from long distance hauls (truck/train?/ship?), what good is this?
