Throughout the twenties there were a number of changes in windshield production. In 1924 some local police departments were the beneficiaries of one windshield development. Lincoln touring sedans called Police Flyers came specially equipped with bullet-proof (glass and polycarbonate) windshields nearly an inch thick. In 1926 Rickenbacker offered safety glass as a standard feature all the way around its car. As Ford continued utilizing safety glass, a 1928 full-page ad for the Triplex Safety Glass Company touted, “The new Ford is equipped with a windshield of Triplex — the glass that will not shatter.”  Also in the 20’s Cadillac introduced Non-Shatterable Security Plate Glass.
