(Note that the video is 2X faster than reality).

ISTM that almost all the cyclists who fell made it safely across the
first track, but fell when their front wheel hit the second rail. I
don't know why that is. Do you?

Good observation. My guess(tm) is that the heavier ground loading on
the rear wheel would tend to force the tire into the funnel cross
section rail channel far more than the lighter ground load on the
front wheel.

Of course! "Ye Magicke Greene Paint" solves all problems, doesn't it?

Yep. Anything painted green is owned by the cyclists. Anything
painted black belongs to the cars, buses, and trucks. Anything
painted white belongs to parked cars or pedestrians. Or, something
like that.

Notice how the two riders in the video both cut across the corners.

The two final cyclists shown in the overhead view don't come close to
"90 degree angle" but they came close enough, at least when it was dry.
When it's wet, closer to perpendicular would be better.

Yep, that what I meant by cutting across the (inside) corner.

I notice the speaker said "... taking a lane like a cyclist should..."
but of course, those are fighting words in some quarters.

Careful. The color code of the road, as I previously mumbled,
indicates that anything black belongs to the automobile. In order to
take the lane, a cyclist would need to carry a can of green spray
paint.
