- [Alison Laroza] The most unique part of rally car racing

is, if a regular person were to hear the in-car audio

of a driver and a co-driver,

it would seem like they were speaking gibberish.

(car engine revving)

Right four long turn left five tightens

three minus no cut.

In actuality it's a language that tells that driver

what is coming next.

Right five minus 100.

They really are just the eyes for the driver

before they can get to that spot.

Rally car racing in America is stage racing.

You can have anywhere from 12 to 14 stages,

anywhere from six to 20 miles in some cases.

I mean you're racing other competitors,

but really it's you against the clock.

(pulsing tech music)

So inside of a rally car, we have two people.

We have a driver and a co-driver.

The driver drives the car,

tries to keep it on the road, without wrecking it.

And the co-driver is responsible for reading the notes.

- [Alison] 50 turn a left three tighten right three minus,

no cut.

So for this example, we have 50 here,

so that means before the next note I call

you'll have 50 meters.

And then T for me stands for turn,

which means you'll change roads from the road

that you're currently on.

And then a left three.

Left obviously means your corner's gonna go to the left.

And a three is the degree of the corner.

- [Steve] There's so much information to take

in from the co-driver, in say 120 miles over a weekend,

it could be as many as two to three thousand

different commands that co-driver is reading the driver.

Pretty much that co-driver is the computer of that car.

He or she is gonna get you from point A to point B.

And as a driver, you need to trust what that

co-driver is telling you.

- [Alison] We started as a team when I was 15,

and sometimes I feel like I can simply read his mind.

Six and twenty,

left six over (inaudible).

- [Steve] I really trust what she is telling me,

to the point where if I had to close my eyes

and maybe not drive at race speed,

she could tell me, pacenotes,

and I could still drive blind.

- [Alison] Into left three, into right four.

Right four long up, tightens at T to a right two,

break turn, left three off camber, 40,

into a care left three down,

50 turn left three tightens into a right three minus...

- [Steve] Rallies let me see how one

of my children has grown up

and how they've become.

If I looked at her as a co-driver and not a daughter

or a relative, I'd grab her in a heartbeat.

- [Alison] I'd love to make it a full time career one day

and rally internationally.

And I'd love to just follow in my Dad's footsteps.
