This is not traffic free. This does not account for the vast majority of people who don't know how to drive or merge on a highway. This would fail every real world trial. It can be said there is some beauty in its arrogance though.

Edit: this is clearly (hopefully) satire given those U turns of death in the middle of a highway interchange that cannot be used by the one thing that needs it the most for this to be commercially viable: semi trucks.

Edit 2: I just noticed this isn't an interstate highway intersection but just your regular ol state road intersection. I ate the onion... I hope it was satire at least.
