I'm glad you guys already had this thread going! The graphic posted by glen is awesome, and I'll watch the video again when we get our Vette.
We went to Phoenix and rented a C7 for a weekend for my hubby's birthday last month, and I'll admittedly say I totally cut someone off on the freeway by missing them in that huge blind spot on the passenger side. My husband leans WAY forward and looks all around when he changes lanes always, which I think is silly. On my own car at home, I use mirrors entirely, and look what happened. The blind spot is SO much bigger in this car than my other ones. I was thinking of getting those little blind spot mirrors as an add-on, but also know the mirrors already aren't big so I thought it could be cumbersome. Needless to say, I'm hyper-sensitive about that big no-view area in the pax side now so there won't ever be a repeat of a pissed off person honking at me on the freeway.
I will probably just adjust the mirrors outward as indicated above, but zimm, could you post a pic of your mirror with the blind spot add on that you're happy with? And Al, did you take any pics when you had yours on?
Cheers!
