I am an abysmal motor vehicle driver. At one point I even developed embarrassing road rage - I learned that I do not have the personality to drive in traffic on a schedule while maintaining composure. I wrestled with this for a few years before I learned I must do two of three things:
1) avoid traffic (take back roads, stay off highways, leave at 5AM, etc).
2) avoid schedules (leave early, don't commit to any given time, and don't plan more than one thing in an evening)
3) avoid driving (bike).
That has made me a better driver, ironically, and eliminated road rage.
But Jim, asking a bunch of cyclists about the bias on either side of such an imbalanced momentum equation is not going to find any truths. However I'll point out that I'm passed daily by a huge number of alert, considerate, polite motor vehicle operators. If they all were like that, there'd be far less of an issue. The ones that aren't are a hazard to the general population, not just cyclists.
