90% of problems on modern cars are computers miscommunicating with other computers, out just deciding that some sensor isn’t behaving well enough, so you have to throw the baby out with the bath water.

All I can think of is a gruff, blue collar worker coming home, covered in oil stains. He hangs up his hardhat and lunch pail at the door. “You would not believe the day I had!” He says, “Some jackass put the 9 dies in the 6 press, and I had to spend all morning trying to pry open the hydraulics without fucking them up. After all that, I get a call that the serifs are too long on the ones and they’re getting sorted as sevens!”
