> Swerving is not legal and it's not legal because you might hit something you can't see. If I'm driving down the road and someone pushes a kid in front of my car, I'm very likely to swerve, even if I'm not 100% sure if there is someone next to me. If I hit a car next to me and cause damage/injure people, there is a good chance that a jury would find in my favor because a "reasonable person" (the relevant legal standard in a civil case) would seek to avoid the certain death of a faultless child, even if it means a chance of injury to passengers in a vehicle that might be nearby. I wouldn't swerve if I thought a bicyclist were there, but I would likely swerve into a vehicle, which affords occupants significant protection. And I certainly would not be found guilty of a crime ("beyond a reasonable doubt", the standard in a criminal trial) because it is not criminally negligent to swerve when faced with the certainty of killing a child. Under the "defense of self/others" doctrine, you can do many things that would normally be illegal, if you are doing them to prevent the imminent death of yourself or someone else.
