I hate to think how much has been written on whether icons need to be updated because the picture isn't literal to the device it uses now, compared that link broken years ago and being more abstract representing a concept. I wonder if in a few years when some cars may be driven by hub motors will there be some moaning that the icon in an engine check light needs changing.

There's so many options on what icons could be for the thing they represent you'll never please everyone, why is forwards a right facing arrow and backwards left facing? (Is this swapped for right-to-left languages?) Why not representing Z-depth away/forwards towards/back? What does reload have to do with rotation?
