Thanks for the pictures. I know it was last year when you posted them but they came in handy for me.
I was not seeing water puddling under the car in the hot and humid Texas weather. So I thought there must be a problem.
I put the car on my lift with it running and found the drain line you pointed out and found that it was indeed draining.
What was happening to me is that the AC condensate water would drip onto my transmission skid plate. The skid plate would hold lots of water and after I park and turn off the engine there not be enough condensate to drip over the edge of the skid plate. Glad it turned out to be a non-problem for me.
