Most drip onto the passenger side exhaust and the water turns to steam immediately. There are many discussions here about the "hissing" or "sizzling" noise people here when they turn the car off. Then, some cars don't do that, apparently the water just comes out and drips down somewhere else and evaporates. If your A/C is working fine I say don't worry about it. But here are a couple discussions with pics that will show you what it looks like and where it is. And it is a bugger to get to.

The drain hose for the AC air box is on the fire wall.
The end of the hole/boot is a split design, but the hose can get plugged from time to time, and you need to de-plug the hose/boot. Just put pressure on the end of the plug to open the slotted end, and use a small section of wire to make sure that the hole/boot is clear (as well as the bottom of the air box).
As for water draining out of the hose, all depends. The cold AC coils will pull the humidity out of the air as is drawn through the coils, and this humidity forms/freezes to the coils and as the ice goes back to liquid form, drops off the coils to drain out of the tube. If you are somewhere with low humidity, they there will not be much condensation collecting on the coils/ water draining out of the tube. If you are somewhere with high humidity, then you get more humidity collecting on the coils/water draining out of the hole. Also, it depends on how well the coils are cooling, and the colder the coils, the more they will pull humidity out of the air (ice builds up, and the new hot air coming through the coils helps to melt the built up ice before it builds to the point of ice blocking the coils)
As for why the water really dumps out after you have shut the car down, all the normal layer of ice build up that has formed on on the coils from the humidity melts since the coils are not longer being cooled.
Granted that the below photo is one of AC coils frozen up since there was not enough air flowing through the coils to keep the humidity build up to melting fast enough, it does give the concept of what the humidity is doing in the air as its being drawn through the coils/where the water is comes from.
