I know that Jan Null, the professor that works with Hyperthermia deaths, has talked to General Motors...On their website they posted this article along with a couple of video's that would teach people the dangers of leaving a child in a car. However, only 1-5 of the 36 deaths a year (last year 41) are done intentionally. Teaching parents is not the only solution. We need to request sensors for cars from dealerships and manufacturers, basically everyone that sells them. This would not be occuring had they not developed the air bag, so why is it so difficult to create a sensor as well. I realize MONEY is the root of the problem, but how much do they spend a year in redevelopment of the airbag. Fortunately the airbag saves lives, but in the case of children alone in a backseat it can also take lives. I would buy a car with a sensor, or even pay to have one put in my car....how about you?
