Also, electric cars mostly have a much shorter range than gas/diesel vehicles, so need to charge more frequently.
And electric cars take much longer to charge than internal combustion engines (double-digit minutes to multiple hours, vs. single-digit minutes).
So, really, even if all of these charge points were publicly accessible, there are about two orders of magnitude too few of them to service an electric vehicle fleet of the same size as the IC vehicle fleet.
(It is, however, a very promising early sign.)
