Granted im ignorant on a lot to do with it, but hydrogen engines are a cool concept.Outlawing gas engines is many decades away, if ever. States will grandfather old ICE vehicles in. What is possible is outlawing the sale of new ones. That is what California did. By 2035 I won't be able to buy an ICE Gladiator. But who knows if Jeep will even still be making them in 2035? If they do, they will EVs or hydrogen based.
