I finished second that year, which should have been caused for a bunch of celebration. But it was just tainted by the fact that not only did a driver die, a fellow Dane died. A guy I knew died. That was pretty tough. — So that throw that into the pile of the things that have to be considered is the weather conditions that you mentioned of the track. The weather is dry or wet. — It's a huge part of it. — Even just last year at Le Mans. It was raining and I was out, and I hadn't made a serious mistake at the 24 hours of Le Mans since I did the first race in 2012 where I put it in the sand trap with like four hours to go and we lost a couple of lap getting pulled out, but it didn't actually change anything for our result because that was just how the field was spread out. I'd made minor mistakes over the years

but nothing that really set us out. And at the race last year when it was raining, I first clobbered a Ford Mustang when I made an overambitious pass on a damp part of the track and couldn't stop in time and then felt absolutely awful as I sat in the gravel pit for two laps and knew that our race was over. A race where we were highly competitive. You're not blessed with a competitive car, a competitive team and competitive setup every year. I know how rare that is. So to know that we had had a chance that year and I sort of squandered it felt really bad, but that got compounded. I got back on track, barely made it another stint and then put it in the gravel trap again when it started raining on the entrance into Porsche. So this is part of why racing is so addicting too because the highs are very, very high. When you win a race like the 24 hours of Le Mans. It feels just incredible. There's so much emotion. But if you fuck it up, the lows are very, very low.

— What are the things you're paying attention to when you're driving? What are the parameters? What are you loading in? Are you feeling the grip? Are you basically increasing the speed and seeing what like a constant feedback system effect that has on the grip and you're trying to manage that and try to find that optimal slip angle? Are you looking around using your eyes? Are you smelling things? Are you listening just feeling the wind or are you looking at the field too? Like how'd you not hit that guy at all? You get close with an inches, right? So you have to pay attention to that too. It's really interesting about that specific battle where we're literally a few inches apart. I can't fully explain it, but humans can develop an incredible sense of space. Where I can't see the edge of the back of my car, but I can know exactly where it is. I can have a mental model in my head

that gives me the exact dimensions of this car just that I can run within a few inches of a competitor car or within a few inches of the wall and not hit either when things go well. The car is about two meters wide and it's quite long, five meters. And you can't see everything. The mirrors are actually kind of shit. There's no rear view mirror in these cars. You can't see out the back. You can only see through your two side mirrors. But you formed this intuitive mental model when you get good enough at this. But what I actually pay attention to most is I run a program. What I try to do when I go to a racetrack is I try to load up the best program I know how for every single corner. What's my break point? What's my acceleration point? What's my break trailing curve? And I try to pick up that program in part just by finding it myself and how fast I can go. But even more so than that by copying my professional competitors or not competitors, co-drivers. So I usually always race with a pro.

And modern race cars produce an absolute enormous amount of data, and you can analyze all that data after each outing. You can see an exact trace of how much you pushed the brake pedal, how much you did in terms of steering inputs. When you got on the gas, you can see every millisecond you're losing is evident in those charts. So what I try to do is I try to look at the chart and then I try to load that in and like that's what I gotta do. Oh, in this corner 17, I have to be 10 bar lighter on the brake. So I try to load that program in and then I try to repeat it now. Then there are all the things that changes. Your tires change quite a lot. These tires are made to only last 40 minutes in many cases. Sometimes at Le Mans we can go longer, but at some racetracks they'll last as little as 40 minutes before they really fall off. So you gotta manage that. That the grip is constantly changing. So your program have to suddenly fit those changing circumstances. And then in endurance racing, you're constantly interacting with other cars
