F1 just needs a little improvement in lots of places. The problem is, 'a little improvement' to make racing closer needs changes to be agreed by the people that are dominating the sport. Understandably they will never volunteer those changes.
I'm pretty sure the FIA as the rule making body can force through anything it likes without consensus, it simply means working in advance.
Not sure when cut off point is for unilateral rule changes for next year, it's usually around June/July this year or even earlier.
Trouble is FIA & Liberty are so locked into the negotiations for 2021 and beyond they wont want to rock the boat at present.
The cut-off point for 2020 has been, come and gone (it was March 30). Due to the number of side contracts involved for 2021, its cut-off point is June 30 this year (and then 2022's cut-off is March 30, 2021). Safety regulations and re-interpretations of regulations that do not involve any rewordings are allowed to ignore these rules completely. In 2003, the FIA nearly got sued by McLaren and Williams for breaking these regulations; it was only when they discovered they were a lot more competitive and that Max was willing to break their businesses to remain in the wrong. Of course, McLaren's and Williams' instinct that the regulations didn't do what they were advertised to do was proven correct, as half of the regulations were rolled back in the subsequent two years and in any case 2004 was no improvement on 2002...
