flat oval
名詞
A
type
of
racetrack,
where
the
circuit
is
not
banked
to
allow
for
track
in
cornering,
thus
missing
positive
camber
needed
to
transform
centrifugal
force
into
normal
force
and
traction.
The
shape
footprint
of
the
oval
itself
is
unrelated
to
being
"flat",
as
it
only
deals
with
the
banking
of
the
track
and
not
the
shape
traced
out
by
the
track.
