Not trying to argue, but do they? I have never had RH lug nuts work themselves loose. Also the factory stopped using them, so were the LH lugs marginally helpful, too expensive, or too many tire guys busted the LH studs?
Probably tyre shop guys snapping them off with impact guns, they are still used on trucks mostly Japanese trucks I haven't had RH threads come loose on cars or trucks either but in theory they aren't a bad thing I like them on my 70 cars because they are unusual on cars and I like to keep things original. You can probably change the studs without removing the axle just tap them out and draw the new ones in with a spacer and wheel nut. One good thing about RH threads is most torque wrenches only work this way so if you want to tighten the nuts correctly with a torque wrench it makes it easier (no need for a special wrench).
