@36w4r6, thank you for bringing the subject. I see it as well very important and let me quote you as well: “the use of our phones while driving is for our safety”. Here just to try to explain, one of the SDLC Members is GARMIN having and offering to customers of their modern navigation products application called Smartphone Link. So as I understand usage of Smart Device Link applications is about streaming of live data to the built in (dashboard) car infotainment or navigation system by using (through Bluetooth connection) your SIM card connected to the Internet in order to be able to downstream and inform you on time and accurately about (for example) current traffic jams or incidents or “just” about significant weather change. How Smartphone Link works when connected I need to say that it changes your route automatically (simplifying but not much) and on time if there is an optional one in order to avoid and save your time.
Another example of how can you use live data and link those directly (without Bluetooth) within the particular application would be example of Live HD Traffic information from MapFactor Navigator and this feature also works with free (OSM) maps (within Android). Still for my interest in L5 usage of Live Traffic data for Navigation on Embedded Linux would be involving of Mapbox but this one goes to this this thread.
