The Michigan Left is second nature to me but I can see how it would be very confusing to an outsider. But I think they are far more intuitive than the New Jersey jug-handles.

Regarding the absence of service roads, I think Texas is the only place I've ever been where there is a near guarantee to have a service road run unobstructed in parallel to the freeway. Maybe that's because Texas was able to lay the freeway before the population growth.
