> what if the car is crashed hard enough (or long enough for the battery to run down) that it's beacon is off/broadcasting wrong information? Doesn't that mean we're just back at the situation we're in today? The worse situation? > What if there's fallen tree or a pedestrian on the road? Also, not the situation at hand. Talking about the case where a car has crashed and is letting the cars behind it know that it has done so. It's like electronic flare deployment (or hazard lights.) Don't you think that a lot of lives and livelihoods could be saved if we had such functionality?
