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.
