Google Maps is now reportedly adding a new feature that will tell you about traffic jams more quickly. A new option, called Slowdowns, has been spotted on the app. Using the feature, people can report slowdowns, allowing Google Maps to gather this data more quickly and with increased accuracy. The feature is labelled as either 'congestion' or 'slowdown' depending on your location. The feature is tucked in the new incident reporting button in the Google Maps app.
