The problem here that the Model 3 owner didn’t realize until he was already parked is that the Jaguar I-Pace parked to the right was using the Supercharger that would have normally been used by the Tesla parked in the middle.
That’s no fault to the I-Pace owner since it is the only way he could have plugged in.
The problem is that the Supercharger is designed to work with Tesla vehicles, which all have their charge ports on the back left side of the vehicles.
That’s not the case for other EVs. Some have it on the front left side, like the I-Pace. Others have it in the middle of the front end, like the Hyundai Kona EV.
