We have a few goals, but the big one is to be able to indicate the source of the location data (Core Location versus an external service) by changing how the location point is drawn. This can be achieved through some other UI element, and that is what I will recommend to my team in the short term. Another possibility is to have a vehicle representation when zoomed in fairly close to the ground and then switch to something more abstract, such as the existing blue dot, when zoomed out further.
