Apparently someone thought "pushing and holding a button for 3 seconds" was a better idea than "turn a key." You know, that's not completely insane: https://en

Apparently someone thought "pushing and holding a button for 3 seconds" was a better idea than "turn a key." You know, that's not completely insane: https://en.wikipedia.org/wiki/General_Motors_ignition_switch_scandal https://en.wikipedia.org/wiki/General_Motors_ignition_switch... Although, wow, that's an awful article, skimming it there's only this hint of the root cause: "After being asked by Missouri Senator Claire McCaskill whether a GM engineer had apparently lied under oath, [GM CEO] Barra confirmed that this had indeed happened (or at least seemed to)." The problem, besides GM having a procurement system that assumed people in it wouldn't lie through their teeth about lethal problems, was a single engineer who selected an out of spec switch, and then, for example, slipstreamed a better one into the system without a part number change. (Otherwise we're in total agreement.)
