Do you think it would
a) still drive straight
b) veer to the left
c) veer to the right
d) do different things on carpet vs hard flooring Give a rationale for your answer.

I'd like to see that experiment as well.
My guess would be a slight turn to the right ("C") as the vector addition on the left side (both straight forward) would be greater than the vector addition on the right side (1 @ 45 degrees right plus 1 at 45 degrees left). I'm just not sure if it would be enough of a difference to cause it to turn.
My post before was for a single mecanum wheel roller set to be tight (or significantly different from the others).
