DY: Everyone Tremps in Israel. It’s how you find rides. That should fall under (at worst) Shomer Pesaim Hashem. No one has stopped Tremping and it hasn’t happened again. And not knowing the wiring is bad doesn’t make it Bidei Shamayim. It’s part of life to make sure your appliances are safe. It wasn’t a Neis that it exploded.
