Quite true, O'l Chap, quite trueReading through this thread, I notice the one thing I do the most is missing.
Watch people's heads. Cars, trucks, buses, motorcycles, pedestrians, bicycles, doesn't matter...watch the head.
People are like horses in the fact that they tend to lead with, and follow their head.
If you're coming to an intersection, and the person's head isn't pointed your direction, there's no guessing here, s/he doesn't see you at all.
Even if that person at the intersection's head is pointed at you, don't assume they see you. I've made solid eye-contact with a cager coming up to an intersection, and they STILL pull out in front of me.
If you're behind someone and in a different lane, and their head points toward your lane, get ready, because they'll be in that lane before you know it...whether you're there or not.
If that head is locked straight ahead, they're not observing anything but where their car/bike/motorcycle is going...They're not watching for you, and odds are, haven't noticed you.
If that head is bouncing around like a bobble-head doll...they're paying more attention to their radio than anything else.
If that head is tilted to one side with a hand coming up to it, they're on the phone...avoid them like the plague.
Observing another person's head on the road will give you a second or two of lead time in what that person may do...And that could be the reaction time you need to save your life.
