Bicycles and automobiles should not share the same roads at all.

[nandomrumber]

Not an entirely unreasonable goal.

But also not present reality.

Share the road.

Which isn't unusual in Japan. You see bicycles sometimes trying to force themselves through swarms of people going at maybe 1 mile per hour.
