BEV's are practical today. Much safer than gasoline. Range is adequate.

Every time someone with any credibility says something good about using
hydrogen as a fuel I have to remind myself that I have looked at the
numbers and it is impossible to make hydrogen a practical fuel for
automobiles. The economics of production, transportation, storage and
conversion are insurmountable. Why Toyota and Honda are convinced
otherwise is a total mystery.
Hydrogen has only one plus as a fuel. It has the highest energy per unit
of mass. It makes OK rocket fuel when compressed and chilled to a liquid.
Note that the most common rocket propellant is LOX and Kerosene, not LOX
and Liquid Hydrogen. This is purely for economic reasons.
For cars this is a reasonable summary of the issues:
The only issue with BEV's other than initial cost is you can't take road
trips in them (except for Tesla). Otherwise they make ideal commuter cars
assuming you have a place to charge at home or at work. Cost to operate is
currently 1/5 that of gasoline and when gas goes back up to its record
levels it will be 1/8th the cost.
