Co-pilot - merge 2 controllers

[akimba]

Now this is going far and beyond, on the new update you can join to controllers as 1 using the co-pilot option.

is meant to be to help coach crappy players so is like a driving instructor having dual controls?

but what if 1 controller turns left and the other right?
