On a recent weekend I ran two different autocross events, one in Huntsville on Saturday and another in Chattanooga on Sunday. Both days, someone (not the same person) commented that I looked very smooth. How outrageous! Don’t they know that I once authored a blog post entitled Smooth Is Slow?
I guess the car looked smooth from their exterior vantage point. Both persons had been working on course during my run group. I can’t be certain, but I don’t think they were trying to slyly tell me I was slow. I was driving faster than ever. Too fast on Saturday, in fact, to stay off the cones.
Both courses were tight and busy. Inside the car I was working furiously, making a huge number of small, quick corrections at both steering wheel and throttle, moving the weight around, finding each scrap of grip available right at the edge of traction and on the precipice of loss of control. I was very busy and I felt nothing smooth about it! I guess since I didn’t spin, didn’t have any big slides and the tires were howling more or less at a consistent pitch and volume it seemed smooth to the observers.
I discussed this observer-versus-driver disconnect phenomenon in Smooth Is Slow. I re-read it just now. Still happy with what I said back then in one of my very first posts. This has made me ponder a slightly different subject, however, which has a connection to smoothness.
Most autocrossers have run into the following complaint about autocross from track-day junkies, usually when asked why they have no interest in autocross: Autocross is dumb because you spend all day to get 6 runs of 60 seconds each. Just not enough seat-time. On a track day I get 5 sessions of 20 minutes each… that’s 100 minutes of seat-time versus 6 for autocross!
I’ve always thought there was something a little screwy with this position. If you don’t find autocross fun, OK. If you don’t care for the competition and can’t enjoy it while losing, well OK to that also. The seat-time argument, if intended to imply that you become a better driver faster, seems wrong to me.
I’ve found that many of the people who say things like this, despite many hours of time on the track dwarfing the time I’ve spent on the autocross course, are painfully slow when I get out there on track with them. (I’ve done 17 track-days. I like doing them. I’m sure I’ll do more.) Typically, they exhibit car control skills that I think of as mediocre at best, which causes them to drive what seems like a very slow pace in the corners, necessarily leaving a large margin for error. I’ve been thinking about why this might be the case, after all those hours they have on track, and have come to an idea about it.
The idea is this: it seems to me if you want to develop high-level car control skills there’s a fast way and a slow way. The fast way is most accurately measured by how much time you’ve spent at the limit of tire adhesion.
During a day of autocross you get, if properly aggressive, 6 minutes at the limit, more or less. It doesn’t matter what car you are in, how much horsepower you have, or what tires are mounted. Spending time at the limit is what counts when it comes to developing car control.
In that 100 minutes of track driving, the typical, sane person gets how much time at the limit? Zero.
None. Zilch. Not any a’tall, which is infinitely less time at the limit than an autocross gives.
Why is this? Very simple. To get to the limit you must go over the limit. Otherwise, you can’t tell, especially before you are an expert, that you got to the limit. Right? So, what happens if you go over the limit during an autocross? Worse case, you tank-slap spin and that run is toast. Guess what, though? You get to start up again, rejoin the course, and drive the rest of the run at the limit. You’re not out anything except a little tire rubber. Maybe you don’t win your class that day. Maybe you don’t beat anybody that day. You can’t worry about that. This is just practice. All runs are just practice. Some of them, eventually, might win you a trophy, maybe even a National event trophy, but it’s all just practice until you’re running for that National Championship jacket. Maybe even after you’ve won one of those, too.
What happens if you go over the limit on a race track? Worst case, you die. Bummer. Best case, you have an off and return to the pits for an inspection and maybe a time-out. You don’t even get to drive hard the rest of the lap. Rats!
Driving over the limit is really stupid at a track day. Nobody is going to kiss you at the end and hand you a trophy. Therefore, the fast way, trying to drive every moment at 100%, is not available to track junkies. They have to do it differently. They have to do it the slow way. The slow way takes a looooong time (as measured in track minutes) and lot$$$$$ of money, as measured in entry fees, travel costs, brake pads and discs, tire wear, extra brake fluid and engine oil changes, etc. And the kicker is that if you don’t do the slow way right you won’t ever get fast.
How can you drive hundreds of hours at the track and never get fast? I’m not totally sure, but from what I’ve observed you do it by driving consistently well inside your comfort zone. I suspect these folks steadfastly refuse the instructor’s pleading that you are now ready so please try going just a little bit faster. Probably, as soon as they can, they ditch the instructor and just circulate. Having fun. Some of them are really smooth, too.
Which brings up my next point: it’s pretty easy to be smooth at 90%.
What is the track junkie to do to get fast and develop top-notch car-handling skills? Other than doing 50 non-fun autocross events with such paltry seat-time and having to accept losing over and over again. Losing to teenagers in smoking, clapped-out Miatas with mismatched body panels and 300 HP less than you have. Losing to grandmothers. Losing to 85-year olds. Lots of losing in autocross!
You do what all the instructors say: gradually ramp up the speed while working on, wait for it, Smoothness!
Why work on smoothness on the track and not the autocross course? Because what you really need to do is get sensitive. Trying to be smooth helps you do that, in the right circumstance, which is driving just a little bit out of your comfort zone. Not much out, just a little. Do that consistently and you improve.
If you drive on the track, you must drive below 100% if you want to own an operable vehicle at the end of the day, not to mention operable legs. But, if you drive at, say, an average of 95% you will actually vary around that by some percentage…let’s pick 3%, because nobody is perfectly consistent, certainly not the novice or intermediate tracker. That means you’ll wander around in the 92% to 98% range.
So, sometimes, for a brief moment, you actually are very near to the limit. If you are sensitive, driving for extended durations at an average of 95% is close enough to get the feel for what the tires are doing and how weight shifts with every input you make and how that affects the level of traction front to back and left to right and how it affects what the car will do next and how it affects how you can execute the technique your instructor has given you, or the drill/practice/cornering method you have set for yourself. You will develop mad skillz, Bro.
On the autocross course you can use the fast way. Immediately push yourself to the limit and learn to handle it. What will you actually be doing? You’re understanding of the car’s dynamics will expand, you’ll anticipate events earlier, your sensitivity to what the car is doing will naturally increase, you will make corrections better, earlier and faster. You get instant feedback from all angles, including the time on the clock. Looking at data will show how much time each little mistake costs. If you want to win you stop making them. You will develop mad skillz, Bro.
You might even get to the point where someone will accuse you of being smooth.
One last thing. Is one way really faster than the other? Let’s say you do 25 autocross events per year for 5 years. That’s 125 days of your life. I think most people can develop quite good skills with that amount of autocross running, if they do it right.

Interesting: the two methods are not different in total time expended, but very different in seat-time.
Put in the time, either method, and you’ll get there. But, whatever you do, don’t drive the track at 100% (or you won’t last long) and don’t drive autocross at 95% (unless you’re OK with staying slow or you think of your tires like pets and can’t bear to torture them.)
