To answer about this feature specifically: we have it as devs but not exposed to users.
It takes quite some time to make it useful! Now it takes forever to simulate a relatively short route. What’s the point in watching a simulation of 20 minutes for a 4 hour drive when you could already be at your coffee stop 😉
We are a small team (2 devs) and need to spend time wisely. Here I am on the forum (while I should be watching Real - Bayern), in my personal time, to make sure our community is and stays happy 😢 After already a quite intense work week (see the results in the 4.1.3 announcement).
Our users don’t see the need for this (yet) and prefer we spend precious time on other features! If this picks up traction, we will definitely consider it 🙂
