I drove 1800 miles in a Hydrogen Car

Hydrogen as a fuel (It's more liquid energy storage than "fuel") has a lot of potential for aircraft and possibly ship applications. It could work on heavy trucks, but BEV tech will overtake that at this point. For smaller cars, H2 is definitely not the future, despite Toyota's naming. 

Regardless of how good the cars themselves are, the infrastructure to support them just isn't going to get built unless Toyota or another vehicle manufacturer making H2 vehicles aggressively invests in renewable energy generation and builds a network of H2 filling stations, which is exactly how Tesla found the winning formula for BEVs.  Tesla saw such explosive growth because of the supercharger network defeating the range problem, and H2 fuel cell vehicles are showing the other side of that.
