Wow, I never actually stopped to think about the way Google determines traffic but it seems so obvious now. This is a very simple but cool trick, I'd expect to see something like this in an action movie where people need to reroute an important car to a particular street. Anyone have any idea how often this data is updated? So if the guy runs through a street with a cart and it turns red, when will it show up as clea…

I guess an important piece (conveniently left out of this story) is that it does not work if there are other cars on the road, as these cars quickly invalidate the data coming from the slow cart.

I'm stunned how fast Google Maps detects traffic jams. I assume all those smartphones are running car navigation and as traffic detection works by trusting the clients I fear there's no chance to avoid this kind of exploit. Nevertheless it would be interesting to know what's the ratio of correct / malicious clients to fool the system. That migt highly depend on whether Google implemented any detection of faulty clien…

Google maps runs also a lot of the time on background so no active navigation is required. I wonder if the introduction of background location activity notifications in iOS 13 decreased the amount of traffic data gathered from iPhone users.

A similar problem happens during unusual big snowfalls in the country or in the mountains. The primary roads turn red because the cars are going really slow cz there is 50cm of snow. So maps redirects you to secondary roads, where there is nobody and even more snow.

I want one app to track my position at all times. I use google because I’m unaware of another—and I figure they have optimized the energy consumption of doing so. Then again, would be thrilled if someone could recommend an alternate way of doing this on iOS (preferably native). PS this function allowed me to time stamp my location which proved incredibly helpful in a FOFA request with state patrol—got me out of a tic…

An interesting "red but no traffic" phenomenon is in Iceland, with roads which are next to scenery viewing points. The roads are mostly empty in this country, but everyone must've slowed down when they saw the breathtaking scenery, and would pull into the viewing point's parking spot to stop and take pictures. On Google Maps these areas were marked red. On another navigation related topic; I was using Waze in a high-…

This happens on NY 73, which is a road in the Adirondack High Peaks region between the highway and Lake Placid. It’s legit — even though cars are parked, you still need to slow down! I usually avoid Google maps for traveling in areas that I don’t know. It takes you off on stupid routes that save marginal time (if any) too much. Waze is good for interstate travel, but IMO Apple is better for giving you the “right”, lo…
