As more and more cars took to the roads, a rise in accidents was inevitable. When one of these early cars was involved in an accident, it was not uncommon for the driver at a minimum to be injured by flying shards of glass or, far worse, lose his life after going headfirst through the windshield. The latter event was known as wearing a glass necklace. In the teens motorists filed a number of lawsuits against car manufacturers, asserting the car makers were the cause of their windshield-related injuries.
The forties brought even further progress for automotive windshields. In 1947 Studebaker introduced its Starlight coupe with a curved windshield. Far more striking, the avant garde 1948 Tucker automobile came with "Pop-Out" windshields. Libbey-Owens-Ford manufactured them. A Tucker sales brochure explained that the "laminated safety glass [was] mounted in sponge rubber fastening so that a hard blow from within will eject it in one piece." It was also that year that Buick, Oldsmobile, and Cadillac added compound-curved windshields to their cars.
From 1936 to 1959 safety glass was used in all save the rear window of cars. In the late 1950s, though, car manufacturers were looking for a cheaper option and began using tempered glass for side and rear windows. Besides saving on cost, tempered glass made it easier for rescuers to cut into a vehicle to free trapped passengers. Some argue, however, that tempered glass should not be used on side windows since tempered glass windows will not prevent partial ejection in side collisions or rollovers. Another disadvantage with tempered glass is that it cannot be repaired as laminated glass can.
