You get offered a choice. Never have a permanent serious accident, but you’re 10x more likely to have them
So the idea is that you can never have a “true” accident. You have 10x the probability of having any accident, and exactly one hour after it happens you get sent back to before it happens with the certitude it won’t happen. If you or someone else is dead, injured, whatever, it won’t carry back. Would you take it?
