For every gallon of fuel burnt theres a gallon of water produced - give or take. The reason you see it when its cold is the exhaust condenses it from vapour into water. When the exhaust warms up it'll flow right out as vapour and you wont see it. Its normal, but usually occurs when you do short journeys- it pools in the muffler and pours out when you move. Try taking it for a good hours journey to clear it. Short journeys are no good for any car- get a bike :D
