I'll add a bit more to the 2 step/looking info:

Go out on a bicycle or something and look as far down the road as you can at a constant speed. Now look straight down at the pavement. Same speed, but notice how much faster it feels when you're looking straight down?

It's a similar effect with your vision. If you look somewhere sooner then you'll have the time to process what you're seeing and be more sure of where you're going. (There's a caveat though: What happens if you decide to 'see' into turn 4 before you take turn 1?)

But if I decide I want to reach a specific point, get my bike lined up towards it, and have a decent sense of speed/timing of when I'll be there -- I can move my attention on to whatever I want to know about next (which gets to Misti's question)
