It's like this Justin
when I ride regularly, my awareness of subtle cues of incoming stupidity from other drivers increases dramatically, to the point where I can predict with a high degree of accuracy what stupid thing another driver is gonna do, even when I'm in my cage
when I don't own a bike, and therefore don't ride for long periods of time, that sensitivity fades, and I'm more apt to be caught by surprise by said stupidity

In short, riding sharpens my awareness and hones my 'spidey sense'
Does that make sense?
