I work out of my truck and need power / climate control often on a job site. There is no way to get past 30 minutes of idle time, even sitting in the truck the whole time. I work out of my passenger seat, so I have to get out and go to the driver's side and do it all over again. I got to be pretty good at using a coat hanger to push the brake pedal from the passenger's seat!
This "feature" really sucks. This one has a horrible possibility of catching someone unaware and killing their pets (or even a kid) over a summer day thinking they can leave the A/C on for a little while while out of the car. Honestly, I would have left my dogs inside during a road trip while we are eating thinking they are cool and comfortable. I'm glad I found this out before I lost my pups. Hopefully GM will change the programming with enough outcry. Seriously, enough with the nannies GM.
