alt Hacker Newsthere's still an inlet and outlet (kinda like hotel pickup/drop off loops). It's not absolutely perfect, but it constrains the space of where kids can dart from every parked car to 2 places.
Also the point isn't the specifics, the point is that the current design is not optimal, it's just the incumbent.
Ok, that's not really a simple change anymore, because you need more space for that. Unless it's really just a drop off queue, but then it's not parked cars, since a parked car blocks the queue.
We would really need to see the site to have an idea of the constraints, Santa Monica has some places where additional roadway can be accomodated and some places where that's not really an option.
