Chevy's Real People, Not Actors ad campaign is no longer credible. So why is it still on the air?

So the same boring jackass has been hosting these Chevrolet "Real People Not Actors" commercials for YEARS now, but we are supposed to believe that Chevy can still find a group of Americans willing to be driven out into the desert and then "quizzed" about the identity of the truck manufacturer the spokeschoad is talking about and be even slightly uncertain as to what the correct answer is?  Really?

If I had been part of this group and heard the woman standing next to me answer "um...Ford?" I would have turned to her and responded "what, seriously?  Are you kidding me?  This guy is only slightly less recognizable than Flo from the Progressive Ads or that Eurodouche dweeb from Verizon.  He's asking you, a Real Person Not an Actor, to name the company that built the truck speeding toward you in the middle of this desert.  And you're totally clueless as to the answer?  What freaking rock have YOU been living under?"

Come on, Chevy.  You can't get away with this anymore.  You had a good run with this schtick- a good run which ended about three years ago, to be honest with you.  But you insisted on beating the bit to death because there's no end to the population of attention-starved jackanapes willing to slobber over your crappy trucks on TV.  Seriously, though- it's over.  Move on.  Because it's just not possible to believe the Looks of Amazement Upon Discovering Oh It's Chevy You're Talking About looks anymore.  It hasn't been, for a long time.  But nobody expected you to get it until long, long after we did.

In fact, every single one of your ads is a celebration of dishonesty.  Your Real People not Actors commercials feature people at least attempting to act.  And your "I just wanted to tell you....just one more thing" yapping jackass is also reading from a script.  This is obvious, and you clearly don't care that you're lying because you have zero respect for your potential customers.  What the hell did we ever do to you?

Again, please.  Stop insulting us and move on.
