The corollary with the electric car is that if a lot of people start driving one, electricity supply will be strained and become more expensive.
And when people get dependant on car charging the power companies and owners of the charging points can start fiddling with the electricity price. In the end, they'll most likely take care of that the total costs will rise to approx. the same level as that of petrol.
That's the way things tend to go. The required, yearly technical inspection of motor vehicles used to be a state monopoly in Finland
some 20 years ago. The price was moderate, but people complained about it anyway, of course. Then they opened it to private enterprise in order to get lower prices through competition. The result was, that the prices started rising, as they simply lifted them as high as people tolerate, and there's too many shops selling the service.
