Infiniti's OEM nav system won't auto zoom, but every Garmin unit I've seen that does auto routing has an auto zoom feature that can be optionally enabled. But the auto zoom function isn't driven by speed.
Instead, it is driven by the distance to the next critical decision point (like an upcoming turn, exit, etc.), waypoint, or final destination. For instance, if on the open highway, and your next decision point is say 100 miles away, the map will zoom out to a large scale that will always show your current location and that next decision point, both visible on the map. As you get closer to the decision point, the map will continuously zoom in step by step, always keeping both your current location as well as the next decision point in view on the map. The closer you get to your decision point, the tighter the scale and the more detail is rendered on the map. Once you have past the decision point, the map will automatically zoom out to the appropriate scale, in order to show current location and the subsequent decision on the route. Very natural, and more relevant than if triggered simply by speed.
I use a Garmin V in my truck and always enable the auto zoom feature. I wish the nav in my M45 had a similar feature.
