This

the

this

Today's

It
moves

much
faster

This
car
will
use
electric
energy
,
not
petrol
or
gasolene
;
it
will
have
batteries
that

instantly
from

It
will
also

In
fact
,
you
won't
need
to
drive
it
;
it
will
drive

You
will
just
need
to

the
computer
:
"
Go

and
the
car
will
go

Also
,
it
will
reach

very

much

today's

It
will
also
be

A

In

,
perhaps
sooner
,
some

will
capture

they
will
store

energy
under
the

and
some
cars
will
be
able

However
you
probably
won't

This

perhaps
,
is

the
