This suggestion is really to show what lap your car is on when you are a backmarker who is really far behind.
The lap counter in the upper left can be confusing for someone that is very far behind or a few laps down. As a backmarker, once the leader crosses the start/finish the counter suits them, not your car. That counter can stay the same, but I really think there should be a 'true' lap counter for your own individual car(s). There should be a separate lap counter... Ideally near the bottom with all the fuel and tire statistics. It would be extremely useful to know which lap you are on as a backmarker for a number of reasons. To avoid confusion and being misled. And most importantly... If you are using a strategy tool or have planned to follow it exactly, you usually know which lap you will end up pitting on. When the current lap counter is something different, it's a bit strange.
I do not know if anyone else feels this way... But when you are a backmarker, it would be extremely helpful to know what lap your car is on. Not the leader.
