I have the same frustration with Google Maps. I have a route I take, and let's say I split it up with A-B-C. now Google Maps tells me that AB-BC takes an hour, but AB'-BC' is 15 minutes faster. It usually turns out that the time delay is on the later leg. So I could take AB or AB', it doesn't matter, and then BC' is the faster choice later on. I wish Google Maps wouldn't show me AB', because it's misleading. At best it should say AB' is the same ETA. But clicking on it means that some route near the end of my drive is now different, it doesn't actually save me time for my current divergence. It's misleading.
