The view out the front of the Tahoe is commanding, and clearly one of the reasons people buy these kinds of vehicles in the first place. The big side mirrors aid in lane changes, although it’s a truck like this where a blind spot indicator like Volvo’s BLIS system would be most helpful. A quick over-the-shoulder gives you a view of thick pillars and headrests blocking the rear view; add people into the mix and you’re suddenly really glad those mirrors are so big. Watching a movie on the ceiling-mounted DVD screen renders the rearview mirror useless. The reverse camera and parking assist sensors simplify reversing, with the rear view duplicated in the navigation screen.
