It's a rather complicated question. Intention matters a lot when it comes to dealing with on-road incidents. If there is no intention, we deem it an "accident", else we deem it manslaughter. The punishment - by courts and by society - are much harsher for the latter.

Can code be "accidental"? Surely not. Someone had an intent to write and implement it. If it fails, its not "accidental"; the system was just programmed that way.

So the question is: are we okay with for-profit companies intentionally writing software that can lead to deaths?
