Toyota FJ Cruiser: flying more or less blind

The greatest weakness of the FJ Cruiser is poor outward vision; it's particularly unsatisfactory off-roading and there's more on that later. The problem is that function has followed form. There are monstrous side blind spots behind the back seats, a small rear window the view from which is hindered by the top of the spare wheel, and outside mirrors that are too small. Toyota tries to mitigate the rear view with a reversing camera in the spare wheel cover but the screen, which is built into the rearview mirror, is tiny and not much use. I'm really liking other aspects of the FJ Cruiser, but this one has me worried.
