construction workers, delivery vehicles, traffic cones.. nothing unreasonable for it to approach with caution, brake for, and move around.
the waymo usually gets about 2 feet away from a utility truck and then sits there confused for awhile before it goes away.
it usually gets very close to these hazards before making that maneuver.
it seems like having a flashing utility strobe really messes with it and it gets extra cautious and weird around those. now, it should be respectful of emergency lights but-
i would see a problem here if it decided to do this on a freeway , five feet away from a pulled over cop or someone changing a tire.
it sure does spazz out and sit there for a long time over the emergency lights before it decides what to do
i really wish there was a third party box we could wire into strobes (or the hazard light circuit) that would universally tell an autonomous car “hey im over here somewhere you may not be expecting me , signaling for attention.”
