Okay. So. I love reincarnation styled isekai. Girl/guy gets hit by unexpected incoming lorry or bus etc...gets reincarnated. We've seen that being done several times over....BUT... what if the anime is from the driver's perspective. And he goes around accidentally sending random people off and narrowly avoids jail and eventually becomes notorious and ends up in jail in season 2. It would start of as slice of life and then slowly change genre as his life goes from peaceful to hell.
