Second
,
the
____________________

is
still
____________________
and
may
not
be
____________________
of
operating
a
vehicle
as
safely
as
a
21
year
old
.
For
instance
,
the
Department
of
____________________
____________________
estimates
that
driving
____________________
thousands
of
decisions
every
minute
to
make
sure
that
the
car
is
in
the
right
____________________
,
at
the
right
speed
,
and
fully
in
control
.
The
developing
brain
may
not
be
able
to
____________________
make
all
of
the
decisions
needed
to
remain
safe
.
____________________
,
there
are
several
other
____________________
that
we
do
not
trust
young
adults
to
participate
in
.
For
instance
,
people
____________________
be
18
years
old
to
vote
,
marry
,
join
the
military
,
and
smoke
____________________
.
In
addition
,
people
must
be
21
before
they
are
legally
____________________
to
consume
alcohol
.
If
we
restrict
young
adults
from
participating
in
these
____________________
,
it
makes
sense
that
we
would
also
____________________
people
under
the
age
of
21
from
operating
a
____________________
____________________
car
on
public
