You have the option to choose any of the other EV makers, but this one EV maker has very fast charging stations worldwide in strategic locations, with lounges and predictable charging rates.

Of the 3 EVs that I drive, only the Tesla I would take outside the city. Even if the others had a much bigger range (they don't) I would not be comfortable outside of the Tesla supercharging network because I've encountered many difficulties with ChargePoint, evGO, etc: stations not working, backed up, slow charging, high cost, etc.

The ecosystem is its charging network because it's very reliable and eliminates range anxiety.
