1959?? In Brazil there were no three-point seatbelt on any car until the 90's!<p>I wonder why, since all our cars were from international big companies (Ford, Volks, Chevrolet...).
They were locally produced, as we had a very closed market, but the technology was available for the big companies to introduce them here. Maybe it was cheaper to built the two-point one and as the brazilian customers didn't have to know that a three-point version was even available, no one complained.
