yes but the idea was lost many years ago
You can make a car run on water if you diffuse oxygen and hydrogen and use hydrogen in your internal combustion engine!But then it is not running on water which was the question. It is running on Hydrogen. So the answer is still NO, you cannot run a car on water.
CArs will not run efficiently on hydrogen gas
no. But they are working on it. They are developing a process to separate the hydrogen from H2O. An engine can run on hydrogen.
no because it needs fuel and hydrogen does not have everything in the combustion triangle
They are working on that. They have machines that can separate the hydrogen from the oxygen. An automobile can run on hydrogen.
hydrogen has three times the potential energy of gas, but it has four times the volume. It would take less hydrogen by weight but it would take more by volume to run a car
There are a couple ways you could run a car on hydrogen. First is to just burn the hydrogen, but you would need a LOT of hydrogen to power a car--about 2 cubic feet of it at 3000 psi (which is the pressure in a tank from a welding shop) per each gallon of gasoline you don't want to use. The other is to make an electric car with a hydrogen-powered fuel cell.
No, you also need oxygen!
Yes, they can but most cars don't.
Yes, it is legal to run a hydrogen car in the US. However, access to hydrogen fueling stations may be limited compared to gasoline or electric charging stations. Currently, there are hydrogen fueling stations primarily in California with plans for expansion to other states.

Honda has hydrogen car. Toyota has hydrogen car. gm is working on hydrogen car.
