Range anxiety, unfortunately it is real.
I am now the happy owner of a Tesla, in the NE corner of Tennessee. Knoxville at 112 miles away is the home of our local EV club and many active clean air proponents I like to support when possible. But to drive there and back at 224 miles I found can be challenging. My first trip down I had great weather and made it there averaging less than 230 w/mile so no real problem getting back.
The second trip I took my wife (not that much extra weight) for an Earth Fest event and the weather was terrible. There was a lot of rain and a good headwind on the way down and even though I drove a steady 50 mph I used 290 w/mile. My wife was very anxious about getting back. I was able to charge (110V) while at the event but the charge rate is VERY slow.
Heading back I had to run the lights and heat and we barely made it back. The low battery light was on and I was in reduced power. The bottom line I found that many things outside of my control can affect performance on a long trip. I am eagerly awaiting the J1772 adapter so I can carge at a reasonable rate when in Knoxville.
So even with 245 (ideal) miles i found I had range anxiety when the conditions were far from ideal.
