If you live in San Francisco and drive a truck than you might be signaling. But if you own a Tesla you are just blending in.
By contrast, here in Idaho owning a truck is just blending in. Owning a Tesla out here would be signaling.
It is interesting how perspective changes so much based on where you are.
In Oregon I swear 80% of the population owns a Subaru Outback. The other 20% owns a Prius. So owning a Subaru in Oregon is just blending in. It doesn't mean anything. But if you drove that Subaru to San Francisco, now everyone thinks you are "outdoorsy".
