Nothing new
It is funny how backwards the automotive industry has always been. Direct injection in a gasoline engine was used by Messerschmitt in WWII and is probably a lot older than that.
Fuel injection, the super charger, hemi head, and multiple valves per cylinder were all invented just after the turn of the 20th century.
Air bags were invented in the 60's and were finally put in most cars in the 90's.
