The vehicles would need to burn off the excess oxygen or do something to prevent its release into the air.
The other issue is getting pure water for the cars. Pure water has to be made, it does not exist in nature. Even rainwater captures impurities from the air, dust and whatnot.

I have a feeling the laws of physics would get in the way of that idea.
Pure water + energy -> hydrogen + oxygen -> fuel cell -> electricity + pure water + heat
The excess oxygen would be consumed by the reaction in the fuel cell to produce heat with pure water as the byproduct.
The electricity generated by the fuel cell could be used to drive a vehicle. The heat from the fuel cell could be used to separate the pure water from the fuel cell into hydrogen and oxygen. And if all that worked you would have a perpetual motion machine.
Instead of fighting the laws of physics, generate the hydrogen offsite, ideally with clean(ish) energy, then transport it to filling stations just as gasoline is produced offsite and transported to gas stations. A car equipped with a fuel cell would then be an EV with a hydrogen fuel cell rather than a lithium battery.
Hydrogen safety in transport and storage is a big problem but maybe solvable.
