Re: car windshields

[Peter Schoch <pschoch@NAC.NET>]

I have a rather more "graphic" experience with car glass -- both front
and rear winndows.  I am not only a Physics teacher, but also an EMT for
my community.

While the glass resting on the victims, after the crash is finished
happening, is "safer" to remove/clear from the patients, it STILL causes
tremendous lacerations -- especially if no seat belt is worn, it is worn
improperly, or a car seat for an infant is installed improperly.

The only benefit I've seen to "safety glass" is from lowered post
accident lacerations -- the ones that happen as we try to extract people
from the vehicles.  In this case, the "safety glass" is a benefit.
