Thanks for the write up. It's always interesting to see our sport from an "outsider's" perspective.
I'll agree that even though the big names might bring up IPhones, there are a ton of PC/Android competitors as well. The Android Marketplace even has an App for tracking rally cars, developed by NASA (The other major US Sanctioning body).
As per Burns Rally, I realize it's dated. However the community still supports updates and modifications, and I know a number of privateers that use it as a training tool for smaller events with in the US.
Sitting in the co-drivers seat, I would concur with the advice Craig noted as to how technology eases my prep work. When I'm going to compete in a new area, I can research the event venues and use Google Maps/Earth to pull Street View images of intersections, restaurants, and that cabin we're renting in the woods. Whilst on stage or in transit, a super accurate user-calibrated odometer and GPS technologies help make sure you are where you think you are.
I can also distribute information to our crew before the event using email and group chats, and then blast texts or use the HAM radio to talk back to folks in service. Lastly, we try to post updates to the Facebook car on transits and in service (cell signal permitting) so that those fans [er our family and friends] that didn't get suckered into coming along can keep up with the event from the comfort of their living room or office.
So much of what the co-driver does is logistics, so anything that helps to automate the process, or enable better communication will be welcomed within the car.
Thanks again for the article!
