This is the key.
You can just punch in a destination in a Tesla, it'll map out the correct route with chargers. Other cars can usually do this too.
The car will pre-heat the battery for optimal charging temperature before arriving at the charging location. Not all EVs do this, they should. Cold-gating during charging is a big deal when traveling long distances in below freezing temperatures.
A Tesla can also check if there are free spots in the charger. No other car does this as far as I know.
Inasmuch as GM had responsibility to help build Tesla’s supercharger network, I agree.
The fact that an SV startup managed to build itself what might be considered a moat by some regulators in a few years while being laughed at by the legacy carmakers is very ironic.
You aren't just buying a car with Tesla, you are buying an ecosystem that just works.
Legacy automakers had almost a century to create this network. And look at the current reputation and state of their dealership network.
