Hi, All,
This whole scenario reminds me of the joke about the girl in the office calling tech support to find out why her computer wasn't working, only to report at last that the power had been out so she couldn't see if the monitor was plugged in or not. The tech told her, or wanted to tell her, to pack the computer back up and take it back to the store and tell them that the reason for the return was that she was "too stupid to own a computer".
That was back in the day. Today we have a new tech problem. And there are still people who will not RTFM: "read the fine manual", and will forget what it was that the fellow told them when they picked up the car. It is gonna happen. These people know about putting gas in the tank, and how to look at a gas gauge to tell if they will make it to the next off ramp, but they never saw a car that can tell them that if they keep driving that way, you have exactly 32 miles left of charge. What does that mean??? What is Range Mode??? What is full charge???
We drove to Canada and back. During that time I got an email from Tesla saying that my battery was below 10% and I needed to plug in. It was better than that. We had been on far eastern Oregon, and drove over 290 miles in freezing weather at several altitude changes. We stopped to do some top up charging, and even added a few additional miles, and it wasn't enough.
But we knew. The car told us that if we drove like we had been, we would end up short. So we slowed down. And we slowed down some more. We limped into our destination with ONE mile left, but we did NOT have to be towed, because we believed what the car was telling us.
The problem is getting the average driver to figure it out. Not every one can make the switch from old dinosaur technology to the new age, but there will be more and more who "get it", and will be able to drive into the new world with a great big Tesla Grin on their faces.
