I’m sure you know that the Swedish company Volvo released its patents on three point seatbelts so that all auto companies could use them. Pretty amazing.
It was actually around World War I that these kind of safety issues became well known to the public. The Triangle Shirtwaist fire, the books of Upton Sinclair, and the muckrakers started to bring awareness to a lot of formerly ignored problems like this.
Yes that I am aware about, and it actually happened earlier. So cars had three point belts when I grew up, but they were not mandatory to use in the rear seat. (Actually, I think they did not have three point belts in the rear when I think about it, but they had in the front)
