Agreed on paper. But my largest concern is that drivers make many, many anticipatory decisions in split-seconds while scanning for traffic.
If a driver sees a cyclist coming while they approach an intersection and, unaware of the new law, assumes "They are going to stop because that's a red light / that's a stop sign," that's a significant risk for the oncoming cyclist if they mis-judge the velocity of the oncoming car and think they'll be able to clear the intersection before the car arrives.
Everybody drives a bit safer when everybody has the most correct mental model of driver behavior they can have.
