Here's my nomination for one of the best poka-yoke devices ever - the tethered gas cap. I heard a tapping as I drove up Inkster road today after filling my tank at the Mobil station (don't ask - at least I have a little Volvo). Aaah...must have forgotten to close the filler tube. Yes, and I didn't have to drive back to the station to get it. Without the cap being tethered, I wouldn't have even have heard the tapping. I'd just be slopping gasoline all over the place. Thank you, unrecognized engineer!
