I am a mountain biker and I use Strava to track my rides. I like the "Flyby" a lot, and I was thinking that it could be used to help avert a potential crash with other trail users. Sometimes, even and slower speeds, you come around the corner of a narrow single track and "BAM", no matter how cautious you are, you can run right into someone. Flyby already tracks where we are in relationship to eachother. Can't we get an alert or something that another Strava user is coming right at us in say, 100 yards? Like a "Collision alarm"?
Let's do this! :)
