Google Maps to Alert Drivers Over Collisions, Speed Traps The new features let drivers br submit data regarding incidents br they encounter while commuting, such as accidents and slowdowns. It will also alert br fellow Maps users br to their presence. The add-ons follow the rollout of a 'Group Planning Feature' released in September. Many predicted Google would implement the 'Collisions' feature after the acquisition of traffic app Waze in 2013. User submitted data is considered to be a big reason why Waze became br popular enough to be bought out. There's no word yet if they will roll out everywhere or if Google is just br testing it out.
