The main thing about these chargers is that nobody is monitoring them. At a gas station, an attendant is usually less than 20 feet away, and if anyone has a problem, they come talk to that person immediately. That attendant usually can't fix the problem on their own, but they can take steps to get it fixed quickly.
By contrast, electric charging stations are typically at the far end of a vast sea of parking. There's nothing, and nobody around, so vandals take advantage, and even when they don't, things just break and there's nobody around to tell about it.
And the whole payment scheme is ridiculous. Imagine a gas station that didn't accept cash, or that you needed an app to pay for. Again, the main problem is that there's nobody around to account for when things go wrong.
