Like others have said, I’d love to see them go back to how the timing and scoring was shown, before. I guess I really need to go back and play a short stint with FM1, go replace my copy of FM2 and play a stint of it, then FM3 and FM4, but I think in all of them, the current lap time, last lap time, best lap time, and overall (full race) time were all shown, full-time. That seems correct to me, and is what I’d want to see.
It is important to be able to see these times at any moment, to me, so that I’m not limited to just a few seconds after passing the start/finish to look and see how my current/last lap time compares to my best. If there is a turn immediately after the timing line, it can be too risky to bother checking the time during that window of opportunity, leaving the driver unable to check their times because they’re no longer shown…
Following that, I’d like to see both sector time (no relation to the car ahead/behind me, just my position on track), as well as gap to the car ahead/behind. THESE are the times that can come and go as needed, and be color-coded red/green or marked with +/-… If I’m not mistaken, these times were shown in the previous games, as well. They were vastly important to me, in order to judge whether I can ease up a little or need to push myself harder, or if I have created a sufficient gap to pit without losing position. Incredibly important during a long race. While slightly less important in a shorter sprint, being able to get a feel for how you’re doing compared to the next guy is still very important, at least to me…
Like someone else said, it would also be nice to have simulated mirrors (center rear view, possibly even left and right side views) in the exterior views. As has also been mentioned, ALL HUD elements should be optional. If you want to run with no hud, from cockpit cam, and just have no clue what sort of times you’re running, cool. But for those of us who understand that the HUD can be seen as being simulated crew radio traffic (“so and so is some seconds behind you” → +gap, “that was a good time in that sector” → green sector time, “you need to push harder” → -gap/red sector time/slow lap), it would be nice to have access to as much timing data as we have had before in other Forza titles.
