Signs of progress
At least around here, Tucson, AZ, the fire and police departments really lobby against speed bumps/humps. They believe it makes it more difficult for them to drive fast over them in emergency situations.
On a bike my experience has been that speed humps (broad with a shallow rise) do not disturb a bike at all while speed bumps (narrow with a sharp rise) are really bad at all but the slowest of speeds.
