The main point is with all the engenering and expense that goes into making Tesla's, the windshield should be higher quality on all Tesla's by default, or at least make it an option so the user could pay more up front for a better windshield.
An update today:
Went to a Tesla charging station earlier today that was being worked on by Tesla employees (or at leaset contractors with Tesla shirts on), and I had a brief conversatoin about my Model 3 windshield experience with one of them.
He told me he had a Model 3 and had to replace the windshield twice on his, and that the Model 3 had fragile windshield glass.
He also mentioned there are about 5 grades of glass for windhsields, and his Model Y so far had not had any windshield issues.
As a consumer it would be better to at least have a windshield quality choice, if you know up front there are these different grades on windshield glass available.
Personally I'd rather pay more upfront for a durable windshield that will not have issues, and Tesla does have durability for almost everything in their cars, just not the glass yet.
