I gave it all a good think and came with some extras:
For the mini-map:
1- I think a black track is easier to see and work with, because the background is light blue and white most of the time. It would also be hard (if not impossible) to add the team's colors to it. So, I think if the other teams could be slightly different shades of light grey (or other light colors except blue) and your dots being well distinguished (yellow or red) it would make the mini-map more useful to get information at a glance. The mini-map for Singapore and rainy races would need a small variation as the background would be darker, but I haven't raced in those circumstances yet to know which colors would be good, but following this line would be interesting ?;
2- I would like you to test more in medium-low quality devices and connections to see if it impacts frame rate to avoid 2 frames per lap as it was for some people on launch. Also, would we see the entire track or just partially on mobile?
3- Would we see the boost being used on this mini-map? If yes, could we get which car is using it (16 ?, for example)?
For the real-time gaps:
1- I don't think a frame by frame update or a lot of mini-sector times like F1 are necessary. Maybe breaking each sector into 3 mini-sectors could be more useful and more ease on data. Adding up a DRS time update would be great too and it would also reduce some of the complains on "dropped while inside 1s". So, from the current 3 time gaps to 10 per lap might be good ?. If not, maybe breaking each sector into 2 mini-sectors for 7 updates per lap would still be useful and interesting to know;
2- I'm not sure if we need the milliseconds on this one as it would even more info than we currently have and would make it too "easy" to save as some boost ?.
I have high hopes for iGP future, but you need to keep us going with a manager game and not watching and giving commands on a racing one ?
