Is that guy serious?
Does he think that if he just starts calling petrol powered vehicles inconvenient that it becomes true?
As several others have pointed out, electric cars are massively inconvenient for those that drive a long commute and/or live in an apartment complex where no charging is possible.
There is simply no means of travel which is more convenient that petrol powered cars. I would love to have an electric car, but for where I live, it simply is out of the question given the massive limitations of today's battery and charging tech.
