Drivers in the US are trained to yield to traffic before entering an intersection. They don't typically yield to traffic when exiting one. For pedestrians moving at walking pace, it's possible for them to see the pedestrian about to cross and yield since the pedestrian will be very close to the intersection.

A cyclist 20 to 30 feet away will not be in view of the motorist who is in the process of accelerating as they exit the intersection.

Making intersecton navigation more complex makes it more likely that someone will make a mistake.
