How much of supercharger reliability comes down to selecting the population of cars, though? I've wondered if deploying chargers that are meant to plug into various vehicles is somehow more difficult, or more likely to damage the charger. Aside from software flaws, by far the most common problem I see with non-Tesla chargers is some current module has taken itself offline due to internal fault detection, leaving the dispenser operating at half capacity or sometimes zero capacity. This has also made me curious as to whether Tesla simply lacks these fault-finding safety devices, or they do the better.
