The article says:

"Botts' dots replace the painted median stripes."

Not IME in CA. They're placed on top of the Scotchlited median stripes
and other lane dividers. Unfortunately, I haven't been to CA since
'86, which, though it feels like only yesterday, was quite a while
ago, in fact.

"Reflective Stimsonite pavement markers are placed at regular
intervals between Botts dot markings to increase the visibility of
lane markings _at night_."

They likewise increase the visibility of lane markings during the day,
since they reflect the sun.
