There's still some nuance that's important. If self-driving cars always sacrifice other road users to protect the driver, self driving cars could be reduce death/injury overall, but there's a question about whether or not this behavior is ethical. And if the training datasets consistently label cars but not other road users, then this bias could be baked in completely by accident. It only needs to be better. A Pedestrian likely has a different definition of "better" than the car driver.
