U.C. San Diego Lines: 20 This is in response to the person who asked why stop for a stop sign if I don't see anyone around. One of the basic problems with this attitude is that, even if you don't see anyone, it doesn't mean that no one is there. Human perception is highly context sensitive: we will only notice what we expect to see. This creates a major problem for bicyclists, because people driving cars don't expect to see a bicyclist. Thus, the driver pulls out of a driveway, makes a turn, cuts you off, etc. He/she simply didn't see you. We, as bicyclists, are human, too (maybe a little more :-)). We tend to be looking for cars. The problem is that we just might run into another bike. Physics isn't my forte, but I'd guess that a bicycle-bicycle collision at high speeds can injure/maim/kill. I've heard of lots of accidents caused by one (pseudo-)biker not seeing the other, and I'm always afraid of some (pseudo-)biker riding the wrong way, running stop signs, pulling the right-turn-U-turn-right-turn trick at red lights, etc., and hitting me. So, please, PLEASE, obey traffic laws. It might save your life, and mine. (Then again, you might be out to get me! :-)) --Alan J. Hu sdcsvax!hu
