I agree the safety latch is a concern but more of concern is that the spinner is coming loose. I know I'm gonna catch holy $h!t for this but here is a pic of my passenger side front Vintage Wheel after about 100 miles. This is with right handed threads on the right side and tightens toward the
front. As you can see from the picture, the safety wire indicates that the spinner has tightened
more after driving. I have a loop in the safety wire that I monitor before each drive.
