Have you accidentally locked a baby in the car in temperatures exceeding 90 or 100 degrees? Judging by the amount of times I hear this on the news, I can show you a whole market of people that find this useful. Calling a locksmith or someone that can break into your car takes time as well as being concerned about potential cosmetic damage. If OnStar can open your car remotely with a single phone call inside of a minute to save a helpless child from being cooked, there's your market. "Will someone please think of the children..."

OnStart opening your care remotely requires more things in the car than preventing the car from locking if the key is inside in the first place would. By the way, I can't lock my car if the key is inside, and the car doesn't have a remote opening feature.
