I just read an online article on venturebeat.com/2015/07/25/california-fuel-cell-car... It seems that a lot of the early hydrogen fuel car drivers are having considerable difficulties refueling their cars as many stations are either malfunctioning, shut down, and sometimes low on fuel. The car makers have no control over them as they are independently owned and operated. Credit Musk for having the genius to conceive of and establish the Supercharger network. Whatever deficiencies it has pale in comparison to ones the hydrogen fuel network is experiencing.
