Circulate it upward and then release it back down by the rear portion of your exhaust cats. It's done to help car keep rear ended seated down during high speeds. It used to drive me crazy at first then I put the car on a lift and noticed that and asked around that's the answer I got.
I thought I read somewhere it was to circulate air through a cooling channel for the lithium-ion battery. Then again, I’m reading this at the same time the bartender (me) was kind enough to provide a couple of heavy pours of Mcallan so I can just as easily be wrong 😜
