Yeah, that's how it works alright. It doesn't cost much to add, but the domestic makers have always been more gun-shy over liability than the Europeans or Japanese. You have to set the trigger level low enough that it will never hurt anybody, ever, and high enough that it will always get the window fully closed every time. The domestics tend to ask a lot more "what if?" questions and worry about a wider range of conditions. Then there is the quality issue: if you have variability in window and weatherstrip fit, then the range of current draw gets wider and it is harder to find a gap between high enough and low enough. So anyway, that's why you don't have it.
