Yeah, Tesla understood that charging infrastructure and selling EVs is a chicken-and-egg problem. Very few people will buy an EV without a large charging infrastructure. Nobody would build a charging infrastructure if there weren't enough EVs sold to use them. So Tesla did both: Sold EVs and built a huge charging infrastructure.

The Tesla Supercharger network is an under-advertised feature.

The third party networks are just so half-assed. Slow (The 19.2 kW J-1772 plug should have never existed, and it took too long for CCS to catch on), expensive, and half the time not even working.
