I would do a little research how hydrogen fuel cells work? There is very little relative hydrogen by volume involved. Gasoline is far more dangerous. The drawbacks are still electric storage. But that technology is closing the gap fast. Some of the future technologies (If can be brought to market profitable?) Is crazy efficient. Thousands of miles on charges that takes minutes?
Popular mechanics has been hinting that internal combustion technologies are obsolete for decades. That time (I believe) has come. Today's electric cars can put our hot rods on the trailer. Tomorrow's? Won't be a fair contest.
