Keep in mind that both El Camino Real and freeway ramps are maintained by CalTrans, not the city. But the one time I submitted a issue about a freeway off-ramp they forwarded the report to CalTrans for me, so it's a good place to start.
Also that intersection is literally the border of Los Altos and mountain view, and is only "partially" managed by Caltrand. I dunno what that means, it's what the lady on the phone told me.
