I don't have the references handy, but IIRC, Toyota accepted a significant US (or CA?) government subsidy for the development of the Mirai with the proviso that a certain number of Hydrogen cars had to be sold by a certain date (10,000 by the end of 2023?) with a proportional penalty for any shortfall. As the deadline approached, they were far behind (8000 or so?) and offered a promotional deal where they essentially gave the cars away (pay $45,000 but get a lifetime free fuel card). I looked at it, but although there is a hydrogen fueling station within a mile of my house, Yelp reviews said it was frequently out of fuel for days at a time, and the second nearest is 60 miles away. Not really an option for a daily driver "round town". -- Lars Poulsen
