By this point you'd think that every possible Google Maps feature would be integrated into the mobile app, but unfortunately there are still a few holdovers from the slightly more advanced desktop version of Google Maps. Google's been working hard to close that gap, though, and another new feature is making its way to mobile, allowing users to set custom departure times outside of public transit.
Previously setting a departure time would be available if you were taking a train or using other methods of public transport that's supported in Maps, but now you'll be able to set it up even if you're driving to get a more accurate arrival time based on traffic around that time, and you can also pick when you'd like to arrive to get similar results.
It's a small change, but definitely a welcome change for anyone that lives near busy and fluctuating traffic conditions. There are still a few things missing like notifications about when you should actually leave to hit your preferred arrival time, but this feature is just barely rolled out into the mobile app so Google still has some time to polish and refine this feature over the coming months.
