A feature of mapping apps that I wish existed: agility.
We’ve all been there. At the moment you mapped your route to your next destination, there was no traffic. As you’re cruising down the road you notice of trail of brake lights distantly in front of you.
You pull up your map application only to find that your clear roadways have transformed into dots of red lines for the next five miles – and your arrival time has been set back 30 minutes. If the map application had the agile ability to automatically re-route based on the new traffic information, you’d be cruising along side streets to get to your destination at a reasonable time.
