On my real-life car I have a ScanGauge E plugged into the OBD port which among other things can be set to show me both the current MPG and average MPG at the same time, which I find very useful. But the game's trip computer UI app will only show one or the other at a time, and it won't let me add a second instance so I could see both. So I would love if the UI app could be set to show both. I did a search and saw other issues relating to the trip computer but not this one before.
