The three-point lap belt that’s widespread at present wasn’t launched till 1959, almost 50 years after the Model T kicked off the age of mass manufacturing.
In The Beginning
Until comparatively not too long ago, security had been an afterthought in automobile design, if it was even thought-about in any respect. It’s not stunning that the primary baby automobile seat wasn’t developed till the Nineteen Sixties.
