Same crap happened to me a few months ago. I was pulling out of a parking spot and heard a loud pop. Turned out some a$$ put a snapple bottle in front of my LF tire. Didn't penetrate the tire, I just took a rag and brushed off what was left sticking to the tires. Come to think of it, I don't ever recall having glass penetrate any tires of any vehicle that I've owned. Nails...well that's a different story.
I really don't get ppl sometimes.
