Enough with the regulations. Idiots will continue to be idiots no matter what you do. Maybe an option or an after market system to be made available. You would think that someone would have already come up with an idea. Maybe you could test for stupidity before they buy the car? Not. Anyway bottom line is we have raised 6 kids, 8 grandchildren, and 2 great grandchildren and have never left or forgot that they were in the car.
