Sounds like progress. Several years ago I described
riding past more
than a mile of cars on a typical commute (not even
properly in the
city), and you simply refused to concede that such a thing
was possible,
never having observed it in your global travels.


I was being nice. I'm still pretty skeptical. Example: David
says the backup is "one mile (literally one mile)" but he
says if he rides past in the door zone he gets gets to the
light in one cycle.

The most common traffic light cycles are one minute, split
evenly between the two directions. OK, maybe this light has
longer cycles - say two minutes instead of one. Is he really
averaging 30 miles per hour as he rides past one mile of
cars in the door zone?

And I'm still curious about which city he's riding - and
now, which city you're riding in.

But again, I think such a situation must be pretty rare.
Give me more information to educate me.

including a non-fatal door at 6:33. I skipped through the 18
minutes, noting there are bike stripes which weren't there
back when I ride North Clark from time to time. Overall, on
one street, you get a representational mix of urban commuter
joys and sorrows.

Nothing wrong with taking a lane when appropriate but it's
not always appropriate. Or reasonable.
