Apple maps tracking with headers feature

I'm not sure if anyone has discussed this yet but I recently discovered that Apple Maps has a tracking feature that's similar to the monitoring in Ariadne GPS. At the bottom left of the maps screen, there is a tracking button. If double tapped once, tracking is turned on. When double tapped a second time, it will say tracking with headers. This feature will give continuous feedback. It will announce the street that you are walking on as well as the streets you are approaching. It will also announce when you are on the streets that you were approaching. One more thing that it does is, it will announce nearby businesses and places to eat. It does tend to talk a bit too much which can be distracting but I find that it's been helpful.
