How about an app for safe cyclists?
The basic rule for safe positioning on the roadway for a cyclist is: "on straightaways, position yourself according to your speed, and when approaching intersections, position yourself according to your destination."
A corollary, which is one of the most important rules of safe cycling, is "never go straight through an intersection positioned such that it is possible for same-direction traffic to turn in front of you." Cyclists who ignore this rule tend to get hit. It's the laws of physics.
If you have bike lanes that guide unsuspecting cyclists into situations like this where they are betting against the laws of nature, then it sounds like what's needed is an app for bicyclists that would guide them to routes without intersections with such lanes.
