Great view rearward but surprisingly hard to use for backing up

I actually installed this unit on a tractor instead, kind of test-driving a theory... Turned out that it really offers a nice view off to the side as well as rearward, so it worked out like I hoped for watching offset implements not directly behind the tractor. I'm still getting used to where not to look when backing up though - only one close call backing into a building so far. No substitute for physically turning around.
