Fast food etc. though is more "stuff that's bad for you taken to excess" as opposed to something that can randomly get in an accident though.

I agree the deer is the better example. You can have patches of unexpected black ice though. I've skidded a few times though never had an accident.

There's certainly gear one uses in activities that have some inherent danger like your chainsaw example. I guesxs things like skis and helmets could be another. The difference with an AI though is that it's the machinery itself that is making the decisions.
