With all the negative threads about cars vs. bikes, I thought I would bring up a positive story. I ride in some fairly congested areas during rush hour, which makes for some pretty interesting riding. And by interesting, I mean incredibly dangerous situations where I have to be pretty aggressive and establish my position. It's the East Coast after all.
As I was heading into one area with a non-existent shoulder and only one lane with oncoming traffic coming down the opposing lane, I could hear a large diesel-type engine coming up behind me. With nowhere to go but the exact line I was already on, I just hoped it would end well. As the truck came around me, I noticed the passenger pushing his side mirror back out. So not only did he give me the three feet safety zone, but the driver must have also asked his passenger to pull the mirror in just in case.
Usually, I wouldn't make much of someone giving me space, because that is what they are supposed to do, but pulling in the mirror showed how much the driver was paying attention, I thought.
