Be sure to watch it in the highest resolution that your screen allows.
Newer GoPro cameras will shoot video in 4k. That's actually all the reason you need to know why this video exists. It is so that you can see shots from Rhys Millen's GRC car in astonishing Ultra HD. Not that having him narrate a preview of the course isn't a great thing as well, it's just not quite as amazing as the view. We're looking forward to seeing more of these as soon as possible, and on other sorts of race cars.
And for any of you with GoPros out there, upload the big files, it'll be worth it.
