I like the format, but I can understand it can be confusing for the fans.

Phillip Island can be confusing for the fans, but it's quite interesting when you understand the complex format and points system.

It's probably a bit too confusing, especially for newcomers to the sport, but it is the same system as last year. Let me explain. This weekend is a dual-driver endurance event with one driver referred to as driver A and the other as driver B. Driver A gets a 20-minute qualifying session to determine the starting order for their sprint race and driver B gets a separate 20-minute qualifying session for their separate sprint race. So that's two sprint races with 75 points on offer from each race.

Now here is where it gets a little confusing because one of those races has to include a pit stop for at least two tyres. I'm not sure yet whether that will be Craig (Lowndes) or me doing the stop. It will depend on what is happening in the race. We have plans A, B, C and D for every contingency.

Now it gets even more confusing because the results of the two sprint races are added together and that determines the grid position for the two-driver 500km endurance race on the Sunday which is worth 150 points for each winning driver. So there is still 300 points on offer for the whole weekend just like there is in every round. I like the format, but I can understand it can be confusing for the fans.

Our cars have arrived down here and I'm finally happy with the ergos in Craig's car which we will campaign for the two endurance rounds at Phillip Island this weekend and Bathurst in October. I feel a bit guilty because I sent the engineers a long list of things I wanted change to make my job easier, but they've now been done and the car is all polished and set to go. The list included things like steering wheel adjustment, a button moved ... silly little things which help us on the big day when things are all happening.

You know, in the heat of the moment you want everything where you expect it to be so you don't have to think about hitting the right button, you just do it by instinct or habit. Which brings me to the 60 Minutes episode last weekend. I was fortunate to be invited back after the segment they did on me last year. This time I was invited to help out in an experiment to see how texting on a mobile phone while driving can affect your abilities. I was called in as a professional driver and they also had a rather new driver there and we had to go through a course while texting.

Although I'm a professional race driver and usually have to deal with making adjustments to roll bars and brakes, with an engineer in my ear and other cars and drivers all around me, trust me it was hard work trying to negotiate the course whilst texting on the phone. It was a real eye opener for me and, I'm sure, thousands of motorists.

As we predicted a few weeks ago, there will be an extra round next year bringing the series up to 16 rounds with an extra race in the Mid East. The full details will be revealed this weekend. I think that's great. I'm a racer and I want to race cars, so the more events the better.
