Greetings, Glazed-ga,
This is a free comment, not an "answer" to your question, and
certainly not the answer you are seeking, since it questions the
premises.
From these two sites, it seems unlikely that Ford advertised the
saftey benefits of laminated glass side windows in 1957:

http://www.cbc.ca/consumers/market/files/cars/windshields/
However, the following site states that generally US models already
had laminated glass side windows in the period 1949-1952. Scroll down
to the text above the last row of photos:

The final footnote at the very end of this site, however, makes clear
that laminated glass side windows were/are a feature of up-market
European models:

This site also suggests that laminated glass side windows are still a
new innovation:

This site indicates that it was tempered glass that was introduced for
side windows in the 1950s:

This site agrees, but suggests indirectly that maybe laminated glass
had been previously used, since tempered glass allowed easier rescue
of persons in accidents:

But then it would seem that Ford would not have first advertised use
of laminated glass in 1957.
Could it be, that the expression "safety glass" has been
misinterpreted to mean laminated glass?
Thinking back to my childhood, I now remember laminated glass side
windows prior to 1957. The first couple of links are about the
"return to laminated glass. Obviously the orientation towards safety
has changed, now less interested in how to rescue people and more in
how to keep them from flying through side windows or prevent attacks.
My apologies for a rather round-about approach to suggest that the
type of "safety glass" advertised in 1957 was tempered glass.
