The thing that most impresses me about Tesla is the charging infrastructure. A good many times I take my Volt or Bolt and try to charge , the charger is in use or broken. Or it’s some charger i haven’t signed up for. And, as I’ve stated, when you try to fast charge the price is all over the place. Then I go by a Sheets and see 10 Tesla chargers, mostly unoccupied. I’m jealous. I understand newer Teslas pay to charge at their chargers. What is the rate and what is the experience? I wish they would include one or two chargers for the rest of us. I’m willing to pay- I just want the consistency in price and availability.
