Before I quit riding my motorcycle, I recalled one important thing: all the way from the Oakland Hills to downtown San Francisco, many (I dare say 'most') drivers would step their cars to the edges of their lanes to make room for me to lane-split. I know there are lots of people who use their phones will driving, but this was clearly intentional, and a large number of people would do it. I was riding a Ducati but in a modern car you won't hear me. So that means that this large number of people were:
* checking their mirrors
* deciding to make room for me
You don't have to make room for me. I can lane split with a car in the center of its lane and I can slow and stop if its close to this side. But people would do it. It's just an everyday kindness - a small measure of friendly consideration and I appreciated that.
I used to ride as well, and I had the same reaction. The sheer number of people who moved over for me (in California) blew me away every time I rode. They'd never hear me coming; they SAW me and made the choice to move over. I constantly felt that I was underestimating how many people were truly paying attention while they were driving, despite how much "we" like to complain that everyone's in their own world and nobody pays attention anymore.
I try very hard to do the same. I did before I rode, and I still do now. I'm a skilled and trained and attentive driver who is rarely distracted. And yet, I am ashamed at how often I am surprised when a motorcycle splits past me. Maybe I shouldn't think so highly of my attentiveness compared to the "average" person.
It's also a lesson on law and culture. Here in CA where it's legal by statute (if not always practiced in a legal manner), and where drivers are aware it happens, and MOSTLY aware that it's legal, the drivers are very kind. In places where it is ILLEGAL, drivers can be a lot more antagonistic and unsafe about the practice. But at the end of the day, the laws are arbitrary; on the asphalt, it's just another human trying to get from one place to another, doing nothing to inhibit the journey of the other.
Just people choosing to be slightly more attentive than they strictly need to be
I ride as part of my daily commute and have for decades. I am still constantly amazed at how frequently drivers move over for me. Especially when there’s a lot of traffic or congestion - these people are stuck going slow, see me going faster in their mirror, and their response is still to move aside for me. I’m eternally grateful to these people.
I like moving over for motorcycles. It's a little thing, but costs me nothing and is totally available as a recognition. Maybe it's like saying, "I see you." I had wondered if it was helpful. Now that you told me it's not necessary, I guess I'll continue doing it anyways.
