I wish there was some beacon or something I could wear while walking that would let cars see me and not hit me or at least slow down. There are just way too many drivers with their heads down looking at their phones. I see a ton of them just blowing through stop signs at full speed every day. It would be nice if their cars would be on the look out since the drivers seem unable to.
