As someone who uses the R1 for work and is constantly driving to and from places during the day, it would be nice to have the maps function know where I'm going next like my Tesla does. In my Tesla, it knows where I'm headed based on the next event in my phone's calendar and that route is already plugged into the nav system when I open the car door. Believe it or not, this is a huge time saver. Then again, the R1's nav system is so unreliable, I have to use my phone's nav to cross check the route and time but at least if it were up in the R1, I could have a general idea of which direction I needed to start driving next.
