My wife worries about me too. If you have a smartphone, google maps and many other apps already let you share your location with selected contacts. When I had my crash on a bike path last year, she had just checked my location and saw I wasn't moving in a location I normally wouldn't stop in. The persons that found me called her using the ICE contacts I'd set up on my phone and told her what they knew and that help was already on the way. So she didn't have to call 911, though she was about to. Location sharing with Google Maps gives gps coordinates so you can inform any emergency response people that need to know. As well it gives a link that sets up a route that will take someone directly to that location if needed.

Since my wreck, I use a helmet with Specialized's ANGI, haven't had any false alerts yet, hopefully I won't have to find out if it works for real crashes. One in sixty-one years is enough for me.


As for the poll, there wasn't a place to say I've used both, but like RWGPS better.
