Slight quibble: I very much agree with your overall point but human-driven cars slam straight into rescue vehicles all the time. They're often intoxicated but not always. There's just something about flashing red lights that attracts driver attention and all too often the car follows.

This is why we put the BRT (big red truck) behind the rescue scene and park it at a 45 degree angle. It weighs 15x as much as a car so it won't move much when a car hits it, and we want the car to bounce off sideways and away from the rescuers (us) when it happens.
