I really don’t like this idea of the car’s telling you there’s a pedestrian. Things will turn into somebody who does not have Bluetooth turned on at the time a car hits them, and the driver’s saying “But my car didn’t tell me somebody was there.”
I think people should just be alert and responsible when they’re driving. Sure, accidents can be tragic. So, pay attention when you’re driving. For that matter, pay attention when you’re walking near busy streets - like your mom should have told you when you were four. How about this, just pay attention to what you’re doing at all times - at least when you’re in public. That will keep people from stopping dead in the middle of croweded malls on Black Friday with 20 people who now bump and crash into each other because they’re all trying to get to Hot Topic - 4 stores down.
I’ve said it before, and I’ll say it again, if you build something idiot-proof, God will come around and build a better idiot.
