Today in non-convivial computing experiences: I found out a modern car can get into a state where it won't turn off. And can't be put into neutral (so it can't be towed).

An OBD2 reader for your make/model + an arduino-OBD2 library helps a car owner grow closer to their hunk of metal for sure!

The good news is I learned where my car's spare tire is. Not where I thought! Conviviality requires some curiosity from me as well.

The first time I learnt that a spare in the US was a baby tire called a doughnut was years into driving there. Had a flat near Joshua Tree, opened the floorboards and thought, "whoa they gave me the tire to the wrong car!"

A car that can't be turned off sounds very much in line with "move quickly and break things".
