I think this was brought up before. But, if not.
Here is a current aerial view of the intersection in question.

If they do not do a massive change to the auto plaza then they could make some changes like this. It would utilize an access road that is not used currently by guests. It would require a repave and striping. They could then install a traffic signal at the existing intersection in yellow.
They could then remove the roadway from the auto plaza to the current world drive and vista intersection, as shown below. They could even leave the weird snake that southbound world drive does currently to get onto east vista.
This would eliminate the possibility of traffic backing up into the auto plaza and even farther, at least as the plaza exists today.
