Let's clear the air.

This means water as an alternative source for the fuel is indeed scientificaly feasible.

You just missed one crucial point. ENERGY.

If we assume entropy to be zero at the moment, the energy used to split water is the same amount of total energy you get from combining H2 & O2.

So assuming you will need to tap into that system to move something, where will you get that excess energy to power your vehicle? If you take 1% of the total energy in the H2O to H2&O2 to H2O system, then it will only return 99% of the total energy. Taking out 50% from the total energy will make the system return 50% of total energy.

Energy assumed to be whatever form you can use: Kinetic, heat, electrical, chemical, etc.

If it takes 100 Kjoules of energy to electrolize a fixed volume of water to H2 & O2, then ideally it will release back 100 Kjoules of back when you combine H2 & O2 to form water.
