Fun fact but the creator of the seat-belt actually gave his patent for free

> This is Nils Bohlin, an engineer at Volvo.[0] He invented the three-point seat belt in 1959. Rather than profit from the invention, Volvo opened up the patent for other manufactorers to use for no cost, saying "it had more value as a free life saving tool than something to profit from"
