Hmm, odd that only me has had any success. I actually made a point of stopping at a stop sign on a uphill road today cuz I've seen so many "doesn't work" comments. Traffic was light, so I waited a couple of seconds with my foot firmly on the brake (I'm pretty sure the car has to be completely stopped, foot on brake, car in D for this to work). I looked out the side window for reference then let my foot off the brake. It immediately rolled back about 1 or 2 inches max and then held. The body actually slightly rocked back and forward again when the wheels were held. I might find a steeper incline somewhere where I can experiment a bit to see when it works and maybe situtations it doesn't that match up with others experiences.

Two climate control systems, one inside and the other at the tailpipe.
