The electric cars were never powered up. Even when parked beside a charger, people simply wouldn't plug them in. When they did, the cars would charge for lengthy periods of time, and hence be unavailable. Gas won.
Despite eletric being half the cost, and more covenient as a one way option, people chose to willingly pay more, and use gas.
Today, the same system is gas only. Electric isn't suitable for this use case.
