Actually I guess we'll making to big a deal about the blind spot:
To quote Raul Julia's Character, (Franco Bertollini-Ferrari Team) from the 1976 movie "Gumball Rally"

Franco: And now my friend, the first-a rule of Italian (Challenger) driving.
[Franco rips off his rear-view mirror and throws it out of the car]
Franco: What's-a behind me is not important.

(Remember, with the Challenger..."objects in the mirror are appearing smaller and smaller")
