To the people considering them: Just be sure you're able to charge at home. While the Supercharger network is a great option to have, and a huge differentiator for Tesla, over 80% of charging is done from home. There is a much greater % of EV dissatisfaction from people who thought they could just use charging stations and didn't need a home charging option. It's also better for your battery. I'd do 98% of my charging from home if I didn't have free supercharging. I take advantage of that when I can, but only because I can for free.
I thought this was going to be the case but with so many free/low cost options around haven't bothered. I went 3 weeks and about 1500 miles without paying for electrons. They next town over has two free chargers exactly two miles away. When I need juice I make it apart of my daily 3 mile walk. When it's raining, my town has 2 chargers two blocks away that cost .12 / KW. When I'm traveling to Asheville, there are 4 free chargers within a mile.
When we can get a real, effective, while-you're-parked level 2, solar-based, free, charging solution - that'll make a solid difference. The second thing will be when there's actually well-spaced, trustworthy, fast charging for road trips. I have the longest range vehicle on the market, it's way more comfortable AND safe than our Subaru, and I still don't know if I want to go more than 1 charge away because of charging anxiety.
That has to be fixed for mass adoption.
