No, I am simply suggesting that your visibility is better when going forward than backwards. When you pull up to a parking space (forwards) you can see whether it's clear to back in, and whether that situation is likely to change in the amount of time it takes to back in (i.e. pedestrians that you can see walking towards your space). Not saying it's foolproof, nothing is. Just saying that when you back out of a parking space you have very limited visibility side-to-side, compared to pulling out forwards. I guess it's less about the straight-backwards view - that is provided by the backlight ("rear window") if your vehicle has one (mine doesn't) or mirrors, or camera - it doesn't seem to me this is the limiting factor, once you have a straight, clear shot at backing into the spot. Or maybe I'm overthinking/overexplaining this?
