Dario Franchitti and Scott Dixon

Of course there were nerves.

The Dixon family had contemplated a project like “Born Racer” for years before they were comfortable letting the cameras in. The movie, which was released in the United States on Tuesday, promises an intimate look at what it takes to be a race car driver. Or, in the case of Emma Davies Dixon, what it takes to watch as a spouse puts their life on the line week after week.

Showing that kind of emotion to the world isn't easy.

“I would be lying if I said I wasn’t nervous how people will react to the documentary,” Davies Dixon wrote on Instagram. “Excited for (our children) Poppy and Tilly to one day show their little ones, a sneak peek into Grandad’s passion/obsession/job. I adore my little family.”

Luckily for the Dixon family, reception so far has been nothing but positive. Scott Dixon's former teammate, Dario Franchitti, said the documentary was "brilliant."

"Born Racer" is available through Amazon, Google, iTunes or on DVD.
