Double Roundabout Interchange

I built this interchange to solve a very specific problem - Motorists were using the exits of my interchange more than they were using the straight highways. This clogged up the ramps and caused all sorts of issues. I tried all sorts of interchanges before I decided on this design.

This design is interesting in that it only really works if drivers are perfect. The inner loop especially seems kind of crash prone in real life. I wouldn't want to drive on it.

Sorry for the lousy thumbnail.
