I get that poor visibility might favor pulling out vs. backing out, but from the standpoint of ease, it's a lot more straightforward (pun intended) to pull in to a confined space. It's a lot quicker and easier to line yourself up parallel to the vehicles next to you (or at least be fairly centered in the space) when you pull in (vs. back in), and then when you need to back out to leave, you can just slowly go straight back until you know the front end will clear the vehicles next to you. There's almost always more room in the aisle than one car length, so it would seem to be a lot easier to take advantage of that extra room when moving backwards. The fact that many vehicles now have back-up cameras makes backing out less dicey than it used to be. Only my opinion......
