>people who could afford an electric car are more likely to take a plane and rent a car when traveling, unless they travel all the time as part of their job, then they’d be using ridesharing exclusively.

What is this based on? I know several people with electric cars and none of us take planes and rent cars on trips unless they're to another country. I drive to California and Austin all the time and the Tesla is the first car that I don't have to stay the night charging for.
