That is a extreme minority of cases. And btw, if you actually use your batteries in a structural way, its not even clear that hydrogen cars will be so much lighter and longer range. There are very, very few cases where BEV will not work. BEV is also much, much, cheaper to operate, so even if its not optimal BEV will still be used over FCV. In those few remote location that you mention (likely a lot less then 1% of the market), gasoline will simply be used. The investment in hydrogen for such a minimal case makes no sense.
