I was looking through this months LROI for some explanation of the picture in the previous issues article about where you can take a bog standard 90 ('How Deep, How Steep). One of the pictures clearly shows the 90 approching the reader with a second door-mirror on the drivers side...?
Why? How?
I assume it's another of those photographs where they've been playing around with photo-shop, making the mud look deeper and the slope look steeper. It's now my standard approach to line up the trees in their photos with the vertical and then assess what sort of gradient the vehicle was REALLY on!
Is it useful for rear seat passengers to be able to see what's coming up behind?
Cheers,
