into an area heretofore restricted. This has been
accomplished by carrying the windshield glass almost
to the top of the body. The window frame construction,
in which the door frame does not extend around
the window, permits window glasses- also to be carried
much higher. The corners of windshield and window
glasses have smaller radii which eliminate widening
of vision obstructions near the glass corners.
Pillars are narrower. The windshield pillar width
has been reduced by one inch. Taking into considerable

tion the front door frame and the ventipane frame, the
total width of the left hand pillar from the angle of
the driver's eye is now only three inches. While this
is a 25% reduction in pillar width, the far more
important fact is that the obstruction to vision has
been reduced 60%. This is because 2¾ inches of the
pillar width is equal to the interpupillary distance
between the eyes, hence offers no obstruction to binocular
vision. Consequently, the apparent obstruction of
the three-inch pillar is in reality only of an inch.
Similarly, the four-inch pillar of conventional cars
offers 1inches obstruction and obscures two and
