Okay, I’ll go first. I once convinced myself that installing a louder exhaust was a legitimate safety feature. My reasoning? If pedestrians and other drivers could hear me coming from a block away, they’d be more aware and less likely to step out or change lanes unpredictably. It was purely for their protection, obviously had nothing to do with how it sounded under a bridge. What’s the most creative stretch you’ve made to rationalize a part or tweak to your car?
