Several years ago, I had one of those "somebody should invent this" ideas:  Incorporate GPS and digital messaging into Citizens Band radios, so that motorists could alert each other to common road hazards, like ice, floods, high winds and - I'm such a tease - speed traps; all with the touch of a button. Unfortunately, CB radios have limited range. For an ice hazard to remain constant through the night, motorists would have to rediscover and rebroadcast the alert, over and over again. That's no good. Eventually, somebody's gonna slide into your Aunt Gertrude's living room. There goes your inheritance, a swell thimbel collection, featuring the complete "Famous Monsters" series from Franklin Mint. Same thing with speed traps. Either way, Gertie's gonna get nailed.
