Is This Corner Tightening Or Opening Up?

You’re in a blind corner, wondering when you can start getting on the throttle. In the absence of other visual references, simply look at the horizon point where the two sides of the road appear to meet. If that point is holding a steady distance from you, the corner is continuing at a constant radius. If it’s moving towards you, the corner is tightening. If it’s moving away from you, the corner opens up and you can begin accelerating. Sound like magic? It works like it too.
