What does it matter.... Only Tesla has anything like a Supercharger Network, and it is expanding constantly. NONE of Tesla's competition is doing any thing for their EV's, therefore only Tesla has a practical EV for long distance travel.
We LOVED our Nissan Leaf, but it was never going to be anything but a local driver. Now, we have over 25,000 miles in less than one year, and in 5 weeks we leave on another 2-week, 9,000 mile, cross-country trip. This time going from northern US down to Key West, FL. We could never do this in any EV other than a TESLA.
We in California do experience some Supercharger overcrowding, but since all of my non-trip charging is at home in my own garage I never experience any wait time.
I have only had to wait my turn two times, once at San Diego - Qualcomm (20 minute wait) while my wife was a couple of blocks away at an appointment. I used the Supercharger just to say I had used it. Never again. The other wait was when we stopped at Rancho Cucamonga on our way home driving south on I-15. That time the wait was about 15 minutes. We will never again have to stop there, either.
Outside of California most of the Supercharger stations we go to have been empty except for us. Never any close to being full.
