I hightly doubt other car companies are gonna do this in a reaonable time frame (3-4 years). They will rely on the dealer network to build out the chargers and suck up the setup cost. Now dealers can potentially finance this with debt and get this done, but I doubt GM or any car company will be able to get consensus from the dealers and roll this ouut fast.
I live in the southeastern US. I have been saying for two years now that Cracker Barrel should be adding DC Fast chargers to each of its restaurants' parking lots. Who cares if the car takes 45 minutes to charge if I can grab a nice meal while I wait.
I used this strategy on my recent Florida-Texas roundtrip in a Model 3. The Baton Rouge Tesla Supercharger is located next to an Acme Oyster House location. I ate a nice lunch while the car charged. I pulled in with a 10% charge and pulled out with about a 90% charge. It was a heck of a lot nicer than eating a hamburger while driving.
In that regard Tesla is having, fir now, clear advantage over traditional car makers. Until, that is, these car makers agreed on a common standard for charging their cars. Once that standard is established (supercharger-like solutions) the risk for third parties to set up charging networks comparable to gas stations became very low.
It is great to see Tesla turn a profit. But it seems to have some down sides, quality for example. Lets hope it is sustainable. I for my part am not convinced it is. We will see who is faster, Tesla at getting mass production right or competitors getting EVs developed and sold.
Laughable, isn't it? Once second of Google would prove it wrong. People literally don't care about reality when it comes to this company. Some PR site says it, and it becomes "fact". The list of things people claim Tesla has done/can do that has no basis in reality is long and growing longer.
