Vanishing Point

1. ## Vanishing Point

After some discussions of how to avoid the rhubarb on unfamiliar corners, it seems that many of us could use an introduction or refresher on "Riding to the Vanishing Point". Here's a "Coles Notes" version of the technique I posted somewhere back in early 2001...

Vanishing Point - Coles Notes Version:

1. Observe where the left edge of the road meets the right edge of the road in your vision. (a long ways away on a long flat straight road, a constantly changing point on most curves)
2. Never ride faster than you can stop in that distance.
3. Never ride faster than you can see, identify and avoid all obstacles within that area.

That's it.

Examples:

1. Constant radius corner
As you approach the corner from the long straight you are on, the Vanishing Point (VP) is essentially at the corner entrance (since you can't see around it), you slow down as you get closer to it, and it doesn't move. As you get close, you can start to see around the corner, and the VP starts to move away from you. Adjust your speed so you are neither gaining on it, or losing on it.
As you go through the corner, the VP will be the same distance from you. As you start to straighten out at the end, the VP will accelerate away from you, allowing you to do the same. The VP picks the point of acceleration, so you don't end up accelerating too early.
2. Increasing radius corner
As you approach the corner from the long straight you are on, the Vanishing Point (VP) is essentially at the corner entrance, you slow down as you get closer to it, and it doesn't move.
As you get close, you can start to see around the corner, and the VP moves away from you. You adjust your speed accordingly.
As you are in the corner, and the corner widens up, the VP starts to accelerate away from you. In the absence of road hazards, you can accelerate after it.
As you start to straighten out at the end, the VP will further accelerate away from you, allowing you to do the same.
3. Decreasing radius corner
As you approach the corner from the long straight you are on, the Vanishing Point (VP) is essentially at the corner entrance, you slow down as you get closer to it, and it doesn't move.
As you get close, you can start to see around the corner, and the VP moves away from you. You adjust your speed accordingly.
As you are in the corner, and the corner tightens up, the VP starts to decellerate towards from you. You slow down too. Remember, if you can't stop within what you see, you're asking for trouble.
As the corner finishes, and you start to straighten out at the end, the VP will accelerate away from you, allowing you to do the same.

This method allows you to deal with unknown varying radius corners with a minimal amount of fuss and hassle. A decreasing radius corner will never sneak up on you, since you've been continually adjusting your speed through it.

The beauty of it is that it automatically adjusts for hedges, parked cars, and other vision blockers. If you can't see the curb because a car is there, the VP will slow down, and so will you. It also dictates a different line through some corners. In order to go the fastest SAFELY through the corner you need to stay within your VP. So, the fastest way through the corner then, is to maximise the VP. This often means a different line than a traditional "racing line".

You DO need the skill of braking and accelerating while leaned over though. You need to at LEAST be able to brake as fast as the corner decreases. Practise this on a controlled area before riding to 100% of the VP on unfamiliar roads.

Make sense?

3. I thought the 'vanishing point' was the exact moment when your "oh shit" realization becomes your reality?

that would be the 'late apex' that many street riders recommend?

i find that if i am honest about my abilities to stop and maneuver within the VP distance, i end up going through many corners very slowly.

perfect sense..... nicely done.... very seldom is there a VP in racing like we get on the street.

Whether it is an early apex, a late apex, a double apex, or other - each corner will dictate differently. And it it often dictated by the sightlines rather than the actual layout of the corner. The same corner that you can early apex with clear sightlines you may want to late apex if there's a car parked at the curb blocking the view of your exit on your very next time through.

That's a bit of a sobering sentence if you sit and think about what it means, isn't it?

It's the point where you and your bike vanish off the road

8. I thought Vanishing Point involved a white charger and not stopping for anything

and Bunnies.... don't forget the freaking BUNNIES!!! LOL

wait...wrong movie.... Never mind....

10. Wow, someone beat Chia posting a picture.

11. Another way to possibly think about it is to be able to see where you'll be. The better the ability to confidently and honestly see where that is, the more likely reaching it. As a last resort, gotta fight off looking elsewhere. Doesn't always work but getting that little extra might be the little that means a lot (or everything). The likelyhood success of this depends more on honesty (and it first) than confidence.
