I drove 1800 miles in a Hydrogen Car

this fuel-cell technology is the answer to 'range anxiety', and 'time to charge' issues...but, the biggest hurdle, is a lack of platinum.
some proposals have been put forth to substitute platinum, however the cost of which will take time to 'authenticate' as to whether it is feasible.  until then, many will be on the fences.
on the other hand, strict combustion of hydrogen gas requires much more voluminous gas tanks - a minimum of 2x the volume.  and then, there's the issue of pressurization of the hydrogen.
is the cost of hydrogen gas too much? - i don't think so; not in relation to the effects of global warming; deforestation, drought, mass starvation, war, mass migration...the effects are currently snow-balling, with year-round wild fires now the norm.  as oxygen levels drop world-wide, greater drought, and lower harvest yields for food will become front and center.
