@Chris R

Try “scratching or cracking” tempered auto glass (any glass except the windshield, which is laminated) without it breaking. Side and back windows in cars shatter, they don’t crack or scratch. Any damage enough to cause even the smallest crack will “pop” the entire door glass, they’re made that way to avoid slicing people up in accidents. Honestly, I’ve tried this; it really works. Really.
