When we really drill down to what great drivers do we are actually trying to define art. We are attempting to do the equivalent of comparing brush strokes between perhaps Leonardo da Vinci and Michael Angelo, if you were a student of the masters you might go so far down the rabbit hole that you don’t want to simply enjoy admiring their works, you are so curious that you want to know how they did it and maybe gain an insight into what made them at the same time unique and great. If you were an artist yourself it would be part of a journey to hopefully one day tap into your own potential for greatness as an artist.
In either case we are after knowledge that can elevate our understanding even to a level that could be considered enlightenment.
While people will call art like the Mona Lisa “perfect” I doubt Mr. da Vinci would, people perhaps ironically at their level are only too aware of their humanity, their imperfections. To the untrained eye this is all nonsense, a fabrication but to the true artist this specifically separates the greats from the pretenders.
The transitional redirect (as I am calling it since I have never heard of it being spoke of let alone being named) is a very fleeting moment where if you look very closely, you see art in driving. I have only seen top drivers do it, it appears on data for such a short amount of time that it probably looks like noise that should be filtered out… but it matters. If the driver can harness it they get a measurable time advantage. It is like seeing a little flare on the end of the painters’ brush stroke, it doesn’t seem to do anything to the untrained eye but it is essential to their ability to produce a masterpiece. What is often amazing is the movement is so ingrained that the artist themselves probably doesn’t even realize they have developed this extra level of skill. It falls into the category of style, it seems subjective but when applied to the absolute objective measure of racing (verses painting) it manifests itself as a measurable increment of time saved so it is worthy of further investigation.
To explore this phenomena you need to accept there is no perfection. Out of every corner from every driver that has ever driven not one driver has ever produced one single perfect corner. Not Fangio, not Senna and not Schumacher and it will never happen. It is important to realized we are human and therefore we always make mistakes. Having said that no two are alike, they vary in severity and that is of course directly tied to the amount of time loss attached to the mistake. The transitional redirects occur in the imperfect moments, they help fill in the imperfections decreasing the time cost of the mistake. To summarize; we all make mistakes but the better the driver the less time is lost with a mistake…and you might guess, this adds up and is the undefined difference between many drivers. We usually look at where the brake and how hard, where they turn and how much and finally where the get on the throttle and how hard but during all of that they are making and fixing tiny mistakes that determine those things so the little adjustments are actually very very important.
The transitional redirects happen in a few ways, in the moment, with the vehicles controls. First let’s isolate steering, now while no two corners are exactly the same or taken exactly the same way (remember we are at a very high level here where people can notice the nuance that the untrained eye wouldn’t even notice), there are distinct patterns that emerge. I am referring to Zerosteer here (if you haven’t read Optimum Drive you need to, it is all explained there) and the steering inputs that go into making each tire and the car generally well balanced at the true limit consistently not just from corner to corner but realizing subtly different inputs in the same corner will be required get you the same net result (due to the continuous changing of the tires grip level, the fuel load and the track surface itself to name the major variables).
I realize this sounds unsmooth, the antithesis of what true at limit “optimum driving” is all about but that is not the case. We have to remember it’s not any single component of our driving that has to be smooth… it is the sum of the inputs that has to add up to smooth (maybe more accurately balanced). Smooth or balanced means that the car for any given point in the corner has optimized rate of turn and grip for that corner at that moment. We can turn it faster (by increasing rear slip angle over the limit for example) but that will decrease overall grip and require us to be going slightly slower. That is the continual balancing act, the tightrope of at the limit driving. There are moments though where we can almost cheat a little. The reason we need to “cheat” is that the corner is never perfect, we tried the perfect balance of steering rate speed and brake release but we got it just a bit wrong so the car didn’t point quite as well as ideal. We could wait it out and let the car slow the amount required to turn that bit more that we need or we can deftly time a sneaky little input, a fix, that allows us to keep almost all of our speed and points the car back on track.
We can also “cheat” a bit with the throttle, taking advantage of some physics properties of the car itself. Load transfer is not instantaneous, depending on the vehicle it usually takes a least a few 1/10’s of a second or longer for the load to shift so if your inputs are quick enough you can affect the tires without affecting to load (the balance). This is Senna’s mid-corner throttle jabs, direct slip-angle adjustments done so fast that the mass of the car doesn’t have time to significantly react. That allows mid-corner speed to stay high and the car is jab by measured jab redirected. A long slow throttle (that is the same cumulative amount of throttle to the several jabs) would induce load transfer to the rear and in all likelihood induce understeer. It seems wrong and to be honest it just might be (technically speaking, more on that later) but just like the virtuoso painter it’s hard to argue with the result.
This grey area driving where the greats seem to throw the rulebook away or a least make mockery of it a bit holds an important lesson for all. When you start flirting with greatness you gain an extra level of awareness that comes from that granular feel. You realize all the rules were merely guidelines to get you here. Simple things like not downshifting and upshifting in corners, late apexes are better (and the list goes on and on) are “rules” that you can regularly break due to the level of feel and connection you now possess. It all has to be earned though and many have found out, try to copy them without first earning the feel and you’ll be off the road at the first corner. Remember it’s a bit more dangerous than overconfidently slapping some paint on a canvas.
Let me explain what is actually happening in these moments. I will use skiing as the analogy for this particular “rule breaking” moment. On skis you carve when fully loaded (pros pulling several G’s) and you change direction unloaded. The skis loaded are very hard (if not impossible) to snap back the other way without unloading them first. Vehicles also have these moments due to load transfer and the effects the load has on grip (remember tires are load sensitive). One occurs at the moment of brake release, now brake release can happen many places, infinite in fact, typically just before turn in (at high speeds or oversteer prone car) to past the apex (downhill, low speed or understeer prone car). We teach the brake release should always be perfectly smooth and that is an excellent guideline and for the beginner/intermediate an unbreakable rule. However, as discussed, there is no perfection. If the brake release is slightly less butter smooth to near abrupt it creates an unweight moment (like the skier) and you can use a transitional redirect to minimize the mistake. You can instinctively flick the wheel into the corner and the car will rapidly turn (just for an instant) and then you take it back to the proper input of the corner. Like Senna’s throttle jab it has to be so fast that you don’t induce load transfer, the car will simply point that extra degree or two and let you straighten the wheel that much sooner. You are only going to ever get a degree or two, the moment is that short, if you leave the extra steering in and you are near/at the limit (like you damn well should be or why are we talking here!) the car will either understeer or oversteer ruining your entry. It can also work in transition from turning one way to another (just like the skier in fact) without any braking required in this instance. It only works when the car is expertly balanced (just again like Senna’s throttle technique). You have to earn the timing and feel through experience.
Another mistake recovery moment where the car will accept a little spike of steering is post slide. It doesn’t matter whether it’s oversteer understeer or a four-wheel drift. All represent an overshoot in corner and should be fixed quickly and deftly (deftly means you don’t over-slow the car too much for the correction). The moment the tires regain traction they will accept a quick redirect. The reason it will take it is that the tire(s) are momentarily just below the limit after the correction. You see this very often on pro driver in car videos. I can’t stress enough how brief these moments are but any change to minimize time lose should not be ignored.
To be honest many good drivers will never feel this or get it to work and probably claim this doesn’t exist. I first notice myself doing it instinctively and then became curious if other did it too and what the heck was it. To my relief I started seeing it but no one was conscious of what it was, I had to point it out. I started researching and found nothing anywhere. It is a very small thing, the time gain is fractional but the obsession with improving has no limits and we also know fractions win or lose races. I really hope you continue your quest for perfection with the rest of us and whether you one day notice you have ingrained one of these techniques, it explains what you are currently doing or perhaps it just helps lift the vale a bit on your racing hero’s YouTube in-car videos making this at the very least worth the read on something very few people would ever notice.
The question though is, of course, is it faster? The answer is it is not faster than a perfect but we hopefully (even though perhaps reluctantly) agree the perfect turn doesn’t exist. In the real world minimizing time loss is the realistic goal and deftly applied by a true great driver these little redirects are how those drivers lose less time for mistakes than merely good drivers and they add up. A top pro to barely a pro is about 2/10’s of a second over a minute and a half lap. Several of these little tiny redirects per lap could easily be a bulk of the time difference, it all matters. The redirects minimize time lose from mistakes, logically knowing that you can confidently push harder not as worried about an overshoot of the limit and it is that very attitude that breeds greatness.
One last observation on Senna’s throttle jabbing because there is a good lesson there. He did it before the mistake, he assumed (pragmatically and subconsciously) that he would have to fix the car mid-corner so he did it always, a habit he picked up from karting. He gave up on perfect and settled on nearly perfect and got on with his job. Was this a good idea? Ideally no, going for the perfect brake release coupled with the ideal turn in that transitions into the optimum throttle application deftly timed with the unwinding of the wheel is faster but we already stated that never happens but by giving up on the chance altogether (as he did) meant there were corners he could have done that tiny bit better than he did. His relative results and speed say it was a good idea but I would venture to say he would have been even faster and more consistent if he aimed for perfection at every corner, after all that the most human thing we can do, continually trying for perfection knowing all-along it is unattainable. Good enough to create the Sistine Chapel, David and the Mona Lisa
