Well, we can compare it with Tesla rollout of their supercharger network.

2012 - 7

2013 - 63

2014 - 380

(based on Wikipedia with cited sources there)

So second year is +56, third +317.

So a comparable rate should be possible.

How many years did it take to get to 7?

Tesla was founded in 2003.

So only 9 years.

They didn't start with the Supercharger network right away. First they had to build the car and survive which wasn't 100% certain.

Still took 9 years to get to 7 chargers. So this article is complaining about a 450% increase in rate of charger building.
