Can I cut side window glass?

Saftey glass is not made to break non violently. It's shards are way more lethal than tempered glass. The safety comes from the layer in between the two layers as you described. Broken tempered glass is WAY less dangerous than Safety glass. Thats why they used tempered glass in doors and close to the floor windows. It turns into 50 million harmless shards.
umm that's laminated glass. I've done all the tricks from Flat glass to finished product for chryslers. Cutting them, grinding them, drilling holes and even making prototypes for different years ie viper in 89, all generations of the minivan and dodge ram from 1968 to 2003 and service runs for the venerable 64-6 barracuda (...ok I hated those) used mainly in front windshields(not counting my old chevy flat side glass and a few other oldies) not commonly called safety glass in the auto industry, cause it ain't.
