My biggest concern when I considered the Mirai a few years ago (during the time they were effectively free) was fuel availability. I just read so many horror stories about people having to drive all around town for hours looking for stations that either didn’t have any hydrogen available, or very limited amounts. The overwhelming sentiment seemed that Mirai owners ended up frustratingly conceding to a full time job that was perpetually trying to fill up while burning through what little they had in the tank in an endless cycle.
Hopefully that’s no longer the case
