> Objects in the driving lane are obstacles, objects not in the driving lane are not. Signs, trees and fire hydrants are typically not in the driving lane, therefore they are not typically problems. > Obstacles in the driving lane should trigger the car to slow down and approach more cautiously, regardless of what they are. This isn't complicated and doesn't require any impossible scenarios. A human can in one moment be next to the driving lane and in the next moment on the driving lane so the speed should be adjusted when an obstacle in the form of a human being isn't on the driving lane.
