My commute invovles riding past a mile (literally, one mile) of cars
that are stopped at stop signs or lights. Riding between them and
parked cars gets me to the light or sign in one cycle. Moving to the
left puts me in stopped traffic.

OK. That's an unusual situation, one that I think is quite rare. We
don't have that situation. And in most of my metro area, if that did pop
up on a certain street, there would be a selection of alternative routes
that would let me avoid it.

If that's what you're dealing with, I'd suggest riding _really_ slow,
and perhaps making noise as you ride. As I hinted to John, at anything
like a normal cycling speed, you cannot possibly stop in time if a car
door pops open as you pass the rear bumper.

Somebody wrote, above, "And we have a $1000 fine for causing an
accident by dooring -- and the cops write the tickets."

What is this intended to mean? You can't trust the cops?
