Engineer answer: being a stack interchange, it’s actually easier to navigate than a cloverleaf because there’s only one exit in each direction instead of separate “A” and “B” exits with an entrance ramp and weaving in between. The complexity in this case simply comes from the fact that it’s superimposed on top of what used to be a street grid, so they added a bunch of exits to local streets.

Big-picture answer: the desire to put freeways there in the first place is the product of mental illness.
