The innovation of the trucker automobile was its safety features, features, features that automobiles of the period did not have. What safety features designed by Preston tucker for his dream car used in today's automobiles ?

Tucker implemented the use of pop out windshields (still used today) and disc breaks, and padded dashboards. I'm pretty sure the disc breaks are the only innovation currently in use. Today's windshields pop out but not upon impact. Impact simply causes them to crack rather than shatter.
