Right on w/ the two second rule. Not only do you have a chance to stop, you also have a chance to swerve and avoid that rusty muffler that appears from the between the tires of the vehicle in front. And, if the idiot behind me is too close, the two seconds may become three. My attitude is space, create it and live in it and always have an escape plan. There's just no one good place to ride in a lane. I'm constantly adjusting to vehicles and potential obstacles which can come from any direction. To identify those things my eyes are constantly moving. Ahead, mirrors, head check, ahead. I look for the little old blue haired ladies, the soccer moms on the phone, the idiot reading the paper or taking notes from his cell phone, the traffic warning / construction signs. There clues tell me where to be and what to be ready for. I don't pace beside vehicles and I don't follow trucks. Trucks drop things and I once saw a tire blow in front of my buddy. What a fricken mess that was and he was really lucky not to splash. Also, you just can't see through em. I also don't hang in the fast lane unless traffic's wall to wall. Not many pass me but I've been scared chitless several times by cars, including cops, that come out of nowhere and blow me away. I think a huge part of survival is mindset. I'm sure they're out to hurt me and it's a constant mental and physical exercise when in heavy traffic. Generally I even enjoy the challenge. I see survival in the traffic jungle as every bit challenging as the curves on 129 and though it's not as satisfying to get to work as to slay the dragon, I find satisfaction in a job well done when I arrive, invigorated and ready to go. Unfortunately, I have to go in to work instead of back out in it.
