With backup cameras it's sorta trivial to backup into parking spaces nowadays.
With backup cameras, which have wide-angle lenses, it is pointless to back into parking spaces: you get a better view of danger pulling out backwards with the camera's view from the back end of your car (or truck) giving you wide angle coverage of what's behind you than you do of danger in front of you looking over your hood from your vantage point in the middle of your vehicle pulling out forward after you backed in.
This effect is probably far less pronounced in a high-cab pickup truck, and is surely more extreme in my favored vehicle, a Mazda MX-5 RF, than in most cars, but it is clearly safer to pull in forward and back out when driving a late model vehicle with a back-up camera and rear hazard warning system, than to back in and pull out forward.
