Water powered car goes brrrrrrr

Actually you would never want hydrogen powered cars from an engineering perspective.

Ideally this would only be producing hydrogen for chemical processes which require a hydrogen feed stock.

You wouldn't want the water to hydrogen plant inside the car but a hydrogen powered car would operate fine from an engineering perspective.

You forgot to read the section on hydrogen storage, infrastructure and safety problems.

But I guess you are correct that we are from an engineering perspective able to make hydrogen powered cars but I would argue that combustion is not a good solution to transportation when proper infrastructure would be able to do without those risks.
