Someone ran over a wrench. I didn't know this was possible

Thats a bit heart wrenching there.

Looks like someone can't dodge a wrench...

Ok, so here's my theory. The first tire kicked the wrench up off the ground and it had not settled onto its side before the second tire reached it. So the second tire pushed against the end of the wrench while the other end was pushed against the road surface, thus providing enough force to pierce the tire.

I call that a spanner. A wrench looks different but does nearly the same thing. Hmm.
