I stumbled across another theory as I was driving my commute back home from work yesterday. I am a left-lane driver. Yes, I probably do go too fast most of the time. I just have issues being behind someone for very long. I also don't like the view or feeling stifled or stuck.
Plus, my epiphany came in the left lane.
I think which lane you drive in has something to do with personality. Now you right-laners can get upset with me or agree with me, it won't matter. It's just a theory and thus may not hold water. Regardless, I'm going to do some personality generalizations.
I think right-lane drivers are the type to observe rules, not try their limits or test tried-and-true methods, possibly lean more toward Type A (although I'm Type A...I never said this was a perfect theory) and introversion. The right-laner looks at the left-laner and thinks, "They're so reckless."
Left-laners are more fly-by-the-seat-of-your-pants, to heck with the rules (quite literally), extroverted, Type B, rule-snubbers, possibly even looking down on right-laners as they cruise on by them, thinking, "They're so boring."
Hopefully I won't get flogged...but these were just some thoughts I had while driving. (The old guy in the Dodge honestly didn't need to be on the road, people. Seriously.)
So...how does this relate to writing? I'm thinking it might be the same! Those in the right lane probably go at a more sedate pace, knocking out their daily word counts every day. Fairly structured writing routine. Left-laners are far more likely to have marathon typing sessions on a weekend where they go into the wee hours and knock out 5000 words like nobody's business. Right-laners probably have the outline all ready to go while left-laners make it up as they type.
Q4U: Is this remotely accurate? For the sake of research, let me know in the comment section which lane you drive in and whether it fits your writing style.
