I have remote AC and although it's been hot here I don't find it very practical to use Remote AC. The reason is I usually would need it when loading groceries or something like that. The problem is it turns off as soon as the car is unlocked. It would be nice to have it on as I'm loading stuff in but I guess I'll have to hop in and turn the car on if I want that. If I was going into the store for five minutes or so it would be nice to leave on but it turns off after three minutes. Also, It would be nice if I could turn it on when walking to the car but still far enough away to let it cool down. Unfortunately by the time I'm in range it doesn't cool it very much. So for me it's kind of a novelty. How are others using it?
