The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
I don't think that's what he meant.
If I understand correctly, you're asking about a trope where Backstory-related deaths are caused by car accidents?
Let me get back to you on that.
We have Bus Crash for when people are sent out of the show and die 'off camera', but it also is playing off the 'killed quickly, without warning, in such a way that doesn't invite a murder investigation' thing you mentioned
I was playing TWEWY and I noticed that, in that game, all deaths are caused by car accidents.
"In A Car Accident" is an easy way to make a character dead, as it's unexpected, but the offender wasn't really a murderer.
I also remember it from the movie Signs, and that new one, Water for Elephants.
We got this yet?
