Stuntman Mike wore Ray Bans in Death Proof. That may not be specifically why he got it, but it could possibly be one of the other reasons why they chose him.
If you actually looked into this, you'd know that Ray Ban sunglasses have been featured in films for decades. Death Proof is one of the hundreds of films that feature Ray Bans.
So QT having a character wear Ray Bans in his film has ZERO to do with it?
