Left hand lug nuts are back, baby!

72,
You keep missing the point. Nobody in their right mind purposely leaves lug nuts loose. However, people get distracted, called away to answer the phone before fully tightening the nuts, have other things on their mind, whatever, & the nuts are not properly tightened. These incidents are what LH threads are for.
Wheels, both L & R side, have come off cars while being driven because the nuts were not tightened so it does happen.
As for the over torqued broken stud........
Obviously you know you have a problem...& you will be getting the bus home....

I have a friend who road races at Summit Point, he is actually an instructor. Had a left front wheel come off the race car. Got distracted changing tires at the track, it cost a lot of money to fix the damage. I started changing tires part time in college and was instructed on Mopar left hand lugs, sure grips, and other knowledge to do a job right. LH lugs are sound engineering, but even Chrysler gave up after 1970? Stupid wins.
