Actually there is quite a bit of water vapor that comes out of the tailpipe in most any engine. The water that you see dripping out of your tailpipe each morning is not from condensation, it is water vapor, a by product of the combustion process. When the engine is warmed up, the water is still there, you just can't see it as it comes out as "steam". I once saw a stat on how much water comes out of an engine going down the road and it was pretty impressive, like gallons per mile as I recall. Another good indication of this phenomenem is the "contrails" or condensation trails left by jet aircraft. In this case the water ejected with the engine exhaust quickly cools at those high altitudes and looks like smoke, but it is really a trail of ice crystals.
