But Honda is working on a way to use smartphones to protect pedestrians from bad drivers. The 'V2P' (Vehicle-to-Pedestrian) tech uses a smartphone's GPS and dedicated short range communications (DSRC) to warn drivers when a pedestrian say, steps out from behind a parked car. So the driver sees a dashboard message warning of an approaching pedestrian (which also notes whether said walker is using phone, texting or listening to music — which sort of shouldn't matter as you, uhm, brake.) The lucky pedestrian gets an alert on their phone telling them there's a DSRC-equipped car coming – that's if, say, actually looking at the road isn't telling you that already."
The lesson here is to always keep your eyes on your smartphone when you're crossing the street. If you get an alert, stop where you are and read it! Relatedly, there's another phone app in development to help you avoid gunfire
