Warnings
for
Electric
Cars
 
Beginning
 
in
 
2021,
every
new
electric
car
 
sold
in
Europe
must
make
 
a
noise.
 
We
expect
cars
 
to
make
 
a
noise.
 
It
 
is
especially
important
 
for
blind
people.
 
Research
shows
 
that
cars running
 
under
electric
 
power
 
 
are
40%
 
more
likely
 
to
 
be
involved
in
accidents
 
 
which
hurt
walkers.
