I drove 1800 miles in a Hydrogen Car

I appreciate the learning opportunity, but hydrogen isn’t the way forward. It has all the issues that gasoline does except for the emissions, and worse infrastructure problems than BEV charging has ever had.  We'd need to build out an entire industry and infrastructure for H2 generation, storage, transport, and fueling stations, not to mention the cars themselves.  BEVs are already here, can be charged literally almost anywhere (if there's a 120V outlet available, it'll work, although slowly), and the existing charge station (L2 and L3) infrastructure is improving by the day.

It’s also less efficient than BEVs - it takes electricity to generate hydrogen (3-4kWh to get 1kWh worth of H2 out, from what I remember reading). It just plain makes more sense to pump that 3-4kWh directly into a battery, rather than adding thermodynamic losses by adding another conversion step into the process. 

Hydrogen is a futuristic pipe dream from decades ago, it has no realistic future anymore for person- to family-scale transportation. Toyota needs to let go of its sunk cost fallacy.
