Well if you want to get technical about it, the LIQUID gasoline, diesel or propane doesn’t burn either, just the vapour it produces.
Water vapor doesn't burn either. Water is what you get when you burn hydrogen and oxygen, its already been burned. In order to get usable fuel out of water you must put energy into it to break the chemical bonds back down, typically electrolysis.
In this sense hydrogen-oxygen combustion is more a like a battery since it cannot be found in nature in large quantities unlike hydrocarbons. You use electricity to split water into hydrogen and oxygen, then compress the hydrogen, put it in a car and burn it turning it back into water, essentially a electric powered car.
Hydrocarbons such as propane or diesel are just energy storage too, we are just taking advantage of solar energy that plants stored millions of years ago using photosynthesis which turned into oil and natural gas in the ground.
