|: inlines wheels can't carve well unless they are placed in a "rocker" position (curved like figure skate blades). I think a 2 part frame might help, but not enough.
I think that would be rrectified by leaning onto the 2 wheel side, at least on one skate at a time. Even rockered skates usually always have two wheels touching. But, I have to admit.....I wondered about the same thing.
