Chances are if you have an Internet connection and even a passing interest in automobiles, you've heard about the "Jalopnik Camaro crash." If not, here's a quick catch-up: Patrick George, who covers a variety of topics for Gawker's cars-and-planes-and-wow-just-wow blog, managed to understeer his way out of a lead-follow pace lap at Detroit's Belle Isle Grand Prix course and into a wall. Damage to the car was relatively minor. He was then removed from the event by GM security, in marked contrast to the kid-glove treatment given About.com writer and part-time The Onion-wannabe Aaron Gold after Mr. Gold managed to put a Camaro ZL1 in the tire wall at VIR for no reason whatsoever.
The veritable blizzard of publicity for both Jalopnik and GM in the week that followed has caused some of the more jaded observers of the autojourno game to wonder if perhaps the whole thing isn't a masterstroke of guerilla marketing. I have to admit I had my own doubts as to the authenticity of the incident, doubts that have not been completely erased by discussions with Patrick and other members of the Jalop staff.
After watching the video a few times, however, I've come to believe that it's probably genuine. I've also come to believe that many of Patrick's harshest critics on YouTube and elsewhere might have found themselves "in the wall" given the same set of circumstances. So if you want to know what Patrick did wrong, why the incident unfolded as it did, and how it relates to an off-track incident I witnessed myself the day before Patrick's crash, then click the jump and I'll explain it all!
If you haven't already watched the Jalopnik video, please do so now – and also, please watch the video above featuring a BMW driver who just can't seem to remember to use his brakes. The second video was taken by the Performance Data Recorder (PDR) in a 2015 Corvette Z51 I was driving around Summit Point's Shenandoah circuit last Saturday. In many ways, it's the same incident seen two different ways. In both cases, the driver fails to slow down enough and then exits the track surface at an angle. The primary differences between Patrick's video and mine are the Belle Isle circuit is surrounded by walls, and the M3 is going much faster.
What I'd like to suggest is that the cause for both incidents was the same. That cause was what I like to call the "out of bandwidth problem". This is not to be confused with Iain Banks' Outside Context Problem. Rather, it's a product of the way the human mind works.
I frequently tell my driving students they can really only learn one thing per instructional session. They can also really only focus on one problem in any given session. To show you why, I'll give you an exercise you can do at home, slightly modified from an exercise given to me by Ross Bentley in a driver-coaching class and also demonstrated in his book, Inner Speed Secrets.
Sitting at your desk, take your right hand and place it on your left knee briefly before removing it. At the same time, raise your left leg off the chair a few inches to meet your hand. Then do the same thing with your left hand and your right knee. Then return to the right hand and left knee. Try to do that in rhythm for a moment. Got it? Now, while continuing your alternating hand-and-knee motion, start counting backwards from 100 while you do it. Still good?
Now try counting backwards from 100 in increments of seven.
I've never had a student who could do it on the first try without some problem. Usually, they say, "100… uh… 93… uh… um…" After they struggle for a few minutes, I show them I can do it effortlessly. I'm not the most graceful or elegant individual, so this is confusing. I then explain I've memorized the numbers. 100 – 93 – 86 – 79 – 72 – 65. I'm not doing the math in real time, I'm reciting a memorized series of numbers I already know.
The brain is very good at doing several things at once, as long as all those things are familiar to it. That's why older drivers aren't as likely to crash while texting or eating or operating the infotainment system. They have more experience with the primary task (driving) and therefore they have plenty of processing power for secondary tasks.
By contrast, how often have you been on the phone with someone who is driving somewhere and is lost? What does that conversation sound like? There are usually a lot of pauses as the person tries to compute new directions or evaluate their surroundings. "So, I was… uh… talking to Bob, and… uh… he said that the numbers look good but… uh, hold on, I just want to see if this is my turn." Talking to someone during their daily commute is very different. We all know our daily commute very well, often to the point that we don't quite remember how we got to the end of it. It's all handled by subconscious routines.
Those of you who have been on a racetrack before probably remember just how confusing your first time was. There was so much to look at, so many new rules, and so many cars that seemed to appear out of nowhere behind you. To make things worse, your car didn't behave the way you expected it to, because it was being operated at a much higher speed. This is why I make my novices stay in fourth gear for their first few sessions, and why I "take the mirror away" by adjusting all mirrors so that I, not the student, watch for traffic. Doing so reduces the number of things on which the student has to focus, and allows him to have more success doing the limited number of tasks remaining. When he can remember the layout of the track, and when he has learned the basics of looking around him in this new environment, I'll let him start shifting before corners, and I'll let him use his own mirrors – but not until he's mastered those other tasks.
Human beings have a limited ability to process new information and perform new tasks in real time. It's a bandwidth problem. You can only focus on a certain amount of sensory data. If a small part of that data is unfamiliar – say, a new car on a well-known track – you can deal with that new data. If you have more than that – a new car, on a new track, with traffic around you – then you have a problem. No matter how experienced you are. You still have a problem. Even Formula One drivers often experience difficulty performing at their best at a new track and developing new features of a car at the same time.
In the case of the BMW who went off-track ahead of me, it turns out that he was "driving his mirrors". He'd been holding me up for nearly an entire lap and I'd been flashing my headlights at him. Instead of letting me by, his ego got involved – That's some bearded hick in a Corvette! – and he decided to try to stay ahead of me and win the trackday. Therefore, his entire attention going into that hairpin turn was focused behind him, on me. How close was I? Was I going to try a pass? Was I going to tailgate him? He was so busy watching me that his mind had no bandwidth left. Therefore, faced with the necessity of slowing down for the corner, his mind chose the more familiar program – let's call it Street Braking – instead of the unfamiliar program of Track Braking. In his effort to watch me, he underbraked and drove off the track into the dirt.
Had he been a more experienced driver, with some racing time under his belt, he would have been better able to multi-task between the challenges of operating the car at its limit and watching my position. But although he was a "black group" advanced driver, he still did not have a lot of experience running nose-to-tail at over 100 mph, so he ran out of processing power and had an incident. This sort of thing is monotonously common at open-lapping days, by the way.
What about Patrick? He's an experienced track rat by media standards, with dozens of lapping days and events to his credit. But listen to his voice as he talks to the camera. Do you hear the bandwidth shortage? In the "uh" and the pauses? What's going on? It's as simple as this: he was trying to do all of the following:
- Operate an unfamiliar car
- On an unfamiliar course
- While evaluating that car in the context of its predecessor
- And describing it to the camera
That's too much to ask out of nearly anyone. I've done it myself, and it's mentally exhausting. To make things worse, our expectations for in-car videos are set by the scripted, high-budget Top Gear episodes where the actors recite a couple of well-rehearsed lines to their cameramen, interspersed with footage of professional drivers. So Patrick is under pressure to make a one-take video sound as polished and insightful as a million-dollar television episode.
No wonder he can't focus on the proper line, or he fails to listen to what the car is trying to tell him about available grip. Those two tasks require bandwidth he doesn't have. By the time the incident starts, he's already mentally maxed-out.
The YouTube commenters on this particular video like to focus on the fact that Patrick has his arms crossed. That's the one thing that he does right on his way to the wall. His consistent hand positioning is the sign of a driver who has received some training at least. But let's analyze the final moments of the crash for a second. He could have avoided the incident by doing one of two things:
- Reducing steering input and braking input, allowing the car to steer out of the situation
- Unwinding the wheel to straight and engaging ABS at full strength.
Either would have been okay. The proximate cause of the accident is that Patrick reacted to a loss of steering traction by winding on more steering – first to the limits of his crossed arms, then further by shuffling – while also braking. This overloaded the front wheels. A more experienced driver would have reduced steering and brake pressure and searched for grip. That's the process that a race driver goes through in every turn: trail-braking until the maximum cornering grip is achieved. When my students make Patrick's mistake, I reach over and unwind their steering until the car grips and we make it through the turn correctly.
But Patrick had no instructor – he had a cameraman and an assignment to discuss the vehicle with that cameraman. That was the ultimate cause of the incident: bandwidth overload. Too many tasks. In a conversation with me, Patrick readily identified that as the problem, with no prompting from me. I doubt he'll do it again.
And in the long run, it was harmless. Nobody was hurt. The car that received damage would have been crushed eventually anyway. There was plenty of publicity to go around and everybody will make money as a result. So if a car crash hurts nobody and benefits everyone involved, is it really a car crash? Process that for a moment, why don't you?
