For comparison, in April Tesla said by year's end it would have 10,000 Supercharger stations in place by year's end. It took the company almost five years to install 5,400 of those. The company also promised to boost the number of normal-speed charging stations (Destination Charging) from 9,000 locations to 15,000 this year. Tesla's first Supercharger rest stops started going online in November.

Tesla has its own woes as well: the company can't produce its $35,000 Model 3 sedans fast enough to keep up with pre-orders.
