ANDY'S TOP
TEN AUTOX DRIVING TIPS

Solo School)
1] Position
first, then speed. Positioning the car perfectly is more important than trying
to attain the highest potential speed. For example, you will drop more time
by correctly positioning the car nearer to slalom cones than you will by
adding 1 or 2 MPH in speed. Same with sweepers (tight line). Same with 90-degree
turns (use all of the track). Also, position is a prerequisite for speed.
If you are not in the correct place, you will not be able go faster. Or at
least not for very long!
2] Turn earlier...and less. To
go faster, the arc you are running must be bigger. A bigger arc requires
less steering. To make a bigger arc that is centered in the same place, the
arc must start sooner (turn earlier).
3] Brake
earlier...and less. Waiting until the last possible second approaching a
turn and then dropping anchor at precisely the correct place so that the
desired entry speed is reached exactly as you come to the turn-in point is
quite difficult to execute consistently. Especially when you consider that
you get no practice runs on the course, and the surface changes on every
run, and you aren't likely to be in exactly the same position with the same
approach speed on every run, etc. Better to start braking a little earlier
to give some margin of error. And by braking less you can either add or subtract
braking effort as you close in on the turn-in point. This will make you
consistent and smooth.
4] Lift
early instead of braking later. Continuing with the philosophy of #3, when
you need to reduce speed only a moderate amount, try an early lift of the
throttle instead of a later push of the brake. This is less upsetting to
the car, is easier to do and thus more consistent, and allows for more precise
placement entering the maneuver (remember #1 above).
5] Easier
to add speed in a turn than to get rid of it. If you are under the limit,
a slight push of the right foot will get you more speed with no additional
side effects. On the other hand, if you are too fast and the tires have begun
slipping, you can only reduce throttle and wait until the tires turn enough
of that excess energy into smoke and heat. Don't use your tires as brakes!
6] Use
your right foot to modulate car position in constant radius turns, not the
steering wheel. In a steady state turn, once you have established the correct
steering input to maintain that arc, lifting the throttle slightly will let
the car tuck in closer to the inside cones. Conversely, slightly increasing
the throttle will push the car out a bit farther to avoid inside cones. It
is much easier to make small corrections in position with slight variations
in the tires' slip angle (that's what you are doing with the throttle) than
with the steering wheel.
7] Unwind
the wheel, then add power. If the car is using all of the tire's tractive
capacity to corner, there is none left for additional acceleration. At corner
exit, as you unwind the wheel, you make some available. If you do not unwind
the wheel, the tire will start to slide and the car will push out (see #6
above).
8] Attack
the back. For slaloms (also applicable to most offsets), getting close to
the cones is critical for quick times (see #1). To get close, we must move
the car less, which means bigger arcs. Bigger arcs come from less steering
and require earlier turning (see #2). Now for the fun part... When you go
by a slalom cone and start turning the steering wheel back the other way,
when does the car start to actually change direction? Answer: When the wheel
crosses the center point (Not when you first start turning back!) How long
does that take? If you are smooth, it takes .25 - .5 seconds. Now, how long
is a typical person's reaction time? Answer: about .5 seconds. Finally, how
long does it take to go between slalom cones? Answer: Typically on the order
of 1 second. Given all of that, your brain must make the decision to begin
turning the steering wheel back the other way just *before* you go by the
previous cone!!
Since this is a mental issue,
a good visualization technique to get used to this is to think about trying
to run over the back side of each slalom cone with the inside rear tire of
the car. To hit it with the rear tire (and not the front), the car must be
arcing well before the cone and the arc must be shallow. Attack the back!
9]
Hands follow
the eyes, car follows the hands. 'Nuf said.
10] Scan
ahead, don't stare. Keep the eyes moving. Looking ahead does not mean staring
ahead. Your eyes must be constantly moving forward and back, and sometimes
left and right. Glance forward, glance back. Your brain can only operate
on the information you give it.
Bonus
Tip: Don't
forget the stuff in between the marked maneuvers! Too often we think of a
course as series of discrete maneuvers. There is typically more to be gained
or lost in the areas that are in between. Pay special attention to the places
where there are no cones.
