Was making a right turn from E. River Road onto Kendrick Road near U of R (Rochester, NY), left front drops and I have this sickening feeling pass through me as I watch my left, front wheel continue on through the intersection without me attached to it.
I think the most surprised person in the whole drama was the poor woman in a Civic who was stopped for the light and watches as the thing heads straight for her. It bounced off her car - no damage.
I was at speed on 490/390 just moments prior - lucky that it didn't let go at 65.
A quick survey revealed that all four wheel studs snapped off almost flush with the rotor, when the wheel parted company, it did an interesting job of custom rolling the left, front fender. The sill extension molding is toast. The rotor is a door stop. The lower A-frame looks like it took a beating, but there does not appear to be any other suspension, transaxle, or engine damage. No leaking fluids. Had it flat-bedded to Cortese Ford - we'll see what the say.
Check your lug nuts, everybody!
