It´s in the interest of everybody, organizers, promoters, sponsors, fans, to watch the drivers do what they are good at: driving fast on stages. Rules could be changed if just take a look from above. And adjust rules so that a driver missing a spare wouldn´t be excluded. (ACM rules differs, if they didn´t, this maybe wasn´t as big problem)
I´ll be silent in that matter now.

Hyundai could show up with their current Rally1 car and maybe, just maybe be enough competitive against Toyota.
