Update: the original car photo can be found here. It's a Lexus LF-A. The weirdest thing is that this car is.... mirrorless... look at the pictures, there are no mirrors whatsoever.
Unless you can make any sense of the fourth picture I received today, I say this whole "Nikon Q" thing is a hoax:
I am filing this under the humor rumor section: the new Nikon car 🙂
