> Rivian's R&D center is in Palo Alto, but their charger map doesn't show a public charger anywhere near there. They have zero chargers of their own in Silicon Valley.

Silicon Valley has one of the highest density of EV chargers in the world, why would Rivian need to build more?

Their goal appears to be covering areas poorly served to expand the places EV owners can go. This seems much more valuable than adding another plug to an already well served urban area.
