You could surely prevent this purely in software. The car knows that is hasn't moved, nobody is sitting in the driver's seat and nobody has touched any controls for 10 minutes. Surely it can switch itself off?
If you add a special switch, that increases costs. Why should car buyers bear extra expenses for less than 100 deaths a year?
Should we require special bathtub sensors that beep when they detects still water because hundreds of people drown in bathtubs each year?
Would've saved this guy's life. That's different.

How much do you think a switch costs?
If you told me that, for less than a dollar, I could save 50 lives, I'd do it in an instant. It's weird to me that you wouldn't.
If you really want that you could have a special "warming" mode.
