Aluminum oxide would be a suitable alternative to glass actually and potentially stronger and more scratch resistant.

I think making the windows out of giant sapphires might make the car slightly more expensive though

If I understand correctly, the Cybertruck glass is essentially transparent aluminum. We saw how that went.

It's sintered from a powder so (maybe) no sheets you can cut to size. Same as Safety glass?

I believe you are describing acrylic sheet which comes in many subsets of density, toughness and flexibility.

You're right. I was refering to acrylic sheets. And some clearly have a poor optical performance which renders them less desirable than actual glass, while others are OK for that matter.

Lexan is another trademarked polycarbonate with many coatings applied to alleviate the inherent faults of the base product for a specific purpose.

I remember Lexan sheets being used more often on racing cars for weight savings.

Home building places stock a common house window glazing grade that tends to not see rock impacts

Common house window glazing in my country is not so easily found on such grade.
