Following your logic, we can ignore Tesla cars that catch fire without crashing, because we can assume they're not going to catch flame when they're used properly; We can assume cars that don't crash aren't going to catch fire anyway, so, even if they may happen, let's throw that data away, because we know our assumption holds true. That's ridiculous.
