This is an absolutely boring one, but did you know part of your seatbelt, right now, could just be colored in?
How about your seat cover? Your steering wheel? Some poor bastard had to go get that out of stock, bring it into repair, go over the entire lot, and take a special pencil to color in those little scratches, or mark it as unrepairable.
I was that bastard for awhile. It sucked. 10 hours going over whatever needed checking that day. An “exciting” day meant a defect hit the line and we needed to hunt it down, hopefully without stopping production.
“Repair” can cover a lot of things, and that was the worst repair work I’ve ever done.
It would be a wealth of social information. Political events, economic crisis, the views of the common man of the time, all have been represented through memery. This is, in a sense, a journal of opinion with a wonderful look across spectrums. They also encapsulate humor, showing where it has and hasn’t changed across generations.
Sure, a massive chunk would be highly irrelevant, but it’s still a solid look into part of a wide culture.
