Mixing Race types in CS

I consider there are several types of races

  • Asphalt
  • Dirt
  • Mixed
  • Cross country
  • Free Roam
  • Drift
  • Drag
  • Track timer

Last one, I explain, I relate this one to the story races you have to do in solo where a count down triggers whenever you get out of the good path. Personnally I enjoyed many of these even if some where too permissive.
Difference between mixed and Dirt, for me Dirt should be a no grip zone for all tires except dirt tires. Mix ed is just those races you are supposed to take a rally car for 20% of dirt race.

What is weird to me is that T10 considered it was not good to mix Asphalt races with Cross country races but mixed Asphalt with Free Roam. In the current state of the game, I don’t see much difference.

My feeling is that I would like to be able to make CS of each type and have cars optmiized for each types but I am not interest in mixing race types. Just like mixing racing and Infected for me, in fact.

Please share your thoughts.

PS : Adding that I would enjoy CS with only 3 races thus quicker from 1 type of race to the other, more chance to get something you like.
