The only times I experienced bike jams or excessively dense bike traffic
was in the Netehrlands and then here on the American River bike trail
during rush hour. So now I avoid rush hour. OTOH its much worse in the
car because while having to ride slower than usual I saw Hwy 50 being a
bumper-to-bumper crawl.

The first time I experienced a bike jam was in Beijing in 1987. As long
as you went with the flow, slow, and made no sudden movements or stops,
you were fine.

The jams now that I see have been on a local MUP in the evening. This
MUP runs from he area around Google and Microsoft out to the south to
Mountain View and Sunnyvale. These are fast moving bicycles and side
trails that lead into the main trail have to yield to the fast moving
traffic.
