If the airbags have a problem which causes them to hurt shrapnel into peoples faces you can't fix that with a software update. and why is being able to push updates to heavy machinery that we routinely have moving at speeds of 60+ MPH a good thing? If you can fix the brakes via software update you can break them too. I'm fine with it if someone going to prison when a software update kills people.
