An Oakland, California, man’s family is suing running and bicycling app Strava after he was killed while making an attempt at breaking a speed record.

The app records a user’s speed and time for stretches of roads. Users can compete with one another by publicly sharing their times for the same areas. After discovering that someone bested his time for a particular route, the man departed to reclaim his title. He ran into a car while traveling at least 10 mph above the posted speed limit of 30 mph.

The lawsuit alleges that the design of the app encourages people to speed, putting them in dangerous, potentially deadly situations. Strava is denying responsibility, citing the fact that it is not involved in the creation of running or biking routes. Strava claims that it removes the ones that are reported to be hazardous.

Bicycle accidents are particularly dangerous because bicycles do not offer the same level of protection that cars do. If you or someone you love has been hurt in a bicycle accident, contact the bicycle accident attorneys of Hull & Zimmerman, P.C., at (303) 423-1770.
