Are there even any limited-access divided highways in California where speeds under 40 mph are safe? I'm not sure what they would have mapped. As the default speed limit for such a highway would presumably be 65 mph (and traffic usually much faster), anywhere with such lowered speeds would presumably have special circumstances that would probably make it unsuitable. The guaranteed 10 second handoff is impressive, however.
