Of many car driving hints that might be provided, this one isn't instinctive - accelerate through curves to gain better traction. It appears that acceleration on a curve would make a car to loose traction and fishtail. It does if you apply too much, but limited acceleration improves traction when taking a curve.

To understand this, let's first look at traction. Then let us see how a car wants to behave when rounding a curve, and then let's put the two together.

Traction is...

Traction is necessary for traveling in the direction we need. When we speed away from a stop, the vehicle moves because it has traction with the road. It goes away from the curb smartly when we accelerate because greater acceleration provides more traction - up to the stage where we've lost traction because of applying too much power to the drive wheels.

If we're on snow and icehockey, nearly any hard acceleration will cause the wheels to slide and also the vehicle to slip in ways which make it behave more in accordance with momentum and gravity than in the direction where we're steering. If we speed up lightly, then we are likely to proceed in a manner and leadership that we expect.



Believe in Term of Vectors...

Now, think of automobile travel concerning a single vector pointing into the direction your automobile wishes to travel. If you're driving straight, there is a vector pointing directly ahead of you because your drive wheels are pushing or pulling you in that way. Easy enough to understand.

Now, envision the vector if you're coasting around a curve. It is pointing forward of you and towards the exterior of the curve because you're going forward yet momentum wishes to take you off the street. Accelerate hard and you eliminate traction and slide in the management of momentum - the vector points hard to the outside of this curve as you slide off the street. It is the same as if you had hit ice on a curve - you eliminate grip and the vehicle travels where momentum and gravity want it to go.

Putting it Together...

In light of this example above where we lost traction on a curve, it's easy to understand that more traction will keep us going in the direction we desire (simply because a loss of grip had the opposite effect). We also found that increased stride provides enhanced grip - up to a point.

Consequently, if we accelerate just a bit, then we are benefiting from improved traction and effectively redirecting the vector to point more towards the desired direction of travel and away from the exterior of the curve. This is why experienced motorcyclists will slow down a bit going into a curve and accelerate through the curve - it helps them"stick" to the road with more grip.

Try it Yourself...

Here is an experiment to show the point. Push with a steady foot round a curve you travel frequently and notice how it feels. Next, the next time you drive round the curve use slight acceleration. You'll see the difference between the three approaches, and it'll convince you that limited acceleration promotes grip in a curve.

Again, of all the driving hints, this one isn't instinctive, but it's true that acceleration through curves supplies a broader margin of safety because of improved traction.
