Having more is a good thing, but gas stations adding them wont move the needle any time soon.
A friend was telling me recently that there aren't many chargers. He lives in Boulder, of all places. There are a million public chargers around Boulder, but they're relatively invisible compared to a gas station, especially if you aren't actively looking for them. When I showed him the plugshare map he couldn't believe it, he thought this stuff was a decade away.
In my experience owning five EVs, public charging isn't really an issue, especially for Tesla and J-1772. If anything, I worry for chargepoint et. al. in the face of so many free chargers in the short term.
That said, there are some weird spots between superchargers if you have a tesla. And if you rely on CCS with the coming onslaught of F-150 lightnings... I wish you good luck and to reconsider. Slow charging speed and crappily maintained CCS / CHaDeMo are really going to suck the life out of you on road trips compared to superchargers. But if you can get by with J1772 then life is good.
