@FreakstyleIts a good effort but some ideas are not even like that in the real world, just like:
always on edge is just not true, some cars yes but there are also the super planted cars - most often the front runners..
There is no fuel mode increasing power output in the races IRL, thats all ERS..
Time trial grip is always the perfect/maximum grip - Online is not and should not but as an option it would be good but IRL it is exactly as you describe, tarmac and how much its rubbered in makes a couple of seconds worth of difference, yes its that huge!..
Traction is actually quite good in the game now..
There are a few such things but most of what you say are good improvements but in the world of maximizing profits you can be happy if we get a few of them in the coming years, not even mentioning how much time all the classic cars and tracks would make to get them actually accurate to real life and not like it was in the past years - the 2006-2008 cars were actually faster than 2010-2013 cars but the other way around ingame
