George, as long as you use Never Seize on the lug bolt threads there shouldn't be a problem with the extended shank bending or shearing off. The lug nolts on our MB vehicles are never a problem to remove; however, I am a DIY'er and replace brake pads/rotors and take loose wheels to our local MB dealer for new tire installation. So I am the only one handling the lug bolts. When I take our MB vehicles for state inspection I request that the tech inspect the brake pads/rotors without removing the wheels. If for some reason the tech must remove the lug bolts I reapply Never Seize and retorque them as soon as possible afterwards.

Lug bolt removal becomes a problem for vehicles that are neglected or mishandled. Without a thin coat of Never Seize the threads can rust in place which requires tremendous force to break loose. Similar situation for lug bolts which are overtightened with an impact wrench.
