From my time spent looking after electrical systems on racecars, I had a horrible mechanic failure. Electrical looms were all white tefzel. Old supplier of semi complete looms laser marked each wire every 150mm or so, new supplier didn't have any markings at all. Mechanic proceeds to drill through one of the thickest sections of the new style main cabin loom that wasn't laser marked, then couldn't understand why I was so pissed. Laser marked wire is extremely common in my experience in aerospace. I don't think I've touched an aircraft that didn't have it.

I had a Braille B128L burst into flames in a v8 supercar while on charge (Braille charger). Filled the car with thick foul smelling smoke. Managed to snip the cables and whip it out, but not without probably doing horrible things to my lungs. Minimal damage to the car thankfully. They're the control battery for the category (and many others). There were plenty of other (less spectacular) issues with the batteries/chargers with other teams too. I've also had some experience with prismatic cell based lightweight car batteries (sponsor supplied) and was pretty horrified. The balacing circuit was on protoboard free floating in the battery enclosure. Unsurprisingly one of the piddly internal terminals broke with all the movement. Horribly cheaply made with every corner cut.
