This seems destined to cause a huge number of car accidents. Instead of looking at the road people will be staring at the screen watching to see if they have turned enough.
I find walking with the map on auto-rotate mode helps friends with spatial orientation problems find their way, as does using sat view.
Personally, I prefer "North Up" view, even in automobile GPS. I find this improves imprinting of location and orientation through the spatial relationships, leaving me better able to navigate without the GPS.
