I was hoping the wheels would fall off, and he'd crash and die, then i could go scavenge the wheels from the wreckage and use them on my car
on a serious note, i do wheel bolts up VERY tight, much tighter than torque wrench recommends, and always make sure people are happy with how tight wheel bolts are before they leave, cos almost anything else can fall apart and you can recover, but if a wheel falls off you're fucked
