Wrong-
Many vehicle manufacturers continue to research H2 vehicles. At the present time, that is the only solution if you want all vehicles to be electric and or emission free. Batteries in their present form will never be able to fulfill public demand for complete solution. Impossible, inconvenient, expensive and time consuming. Something the public has always avoided.
BTW -
Toyota has scrapped nothing. Also can anyone mention a vehicle manufacturer who has not spent billions in research?

Besides Fuel Cell we also have H2 combustion engines. Dont worry, if the world doesnt jump on board fast, China may once again surprise everyone!

This is just my opinion but to think as current EVs as advanced, I just do not personally see it. I have had remote controlled lithium Helicopters and 4 wheel drive trucks for over a decade to 15 or more years.
