Anecdotal evidence: I have charged a grand total of 1 time at the public charging station across the street, due to not planning ahead. Every other time, I charge at home or work. So, for me the balance lies at over 99% private charging. I suspect others have similar experience and this skews the picture quite a bit away from public charging. Apartment dwellers either need to rely on workplace charging or get a (shared) charger installed, but are likely to use more public charging otherwise. So, with more people buying EVs, including those without garage or private driveway, the need for public charging likely increases more than linear. Cor.
