Thanks to Google Maps, you too can see the intersection in all of its glory. Since the right onto Wilson is a yield and you look down Wilson for other cars, people, bikers, and oompa-loompas, you're blocked from seeing everything because of the sign. When checking the leftside of the intersection, I have to look left of the sign and then quickly to the right (of the sign) and assume I didn't miss anyone blocked behind it in the center. It does so well at challenging turning drivers that I think someone in the DOT placed it there at that angle on purpose. It's impossible to accidently position an obstacle like this when it's so good at blocking the view on the left.
