Tesla responded to my email yesterday and said that they are working on an update that will allow ChadeMO.
There are plenty here, but they are slow chargers, except for ChaDemo. Many of our chargers are free event, but 20 miles an hour doesn't help so much.
I charge at home most of the time and it's not an issue. Sometimes though it would be quite helpful. I work in Topeka a few days a week. Yesterday I woke up to a partially charged car because I didn't plug in correctly. I got there and back with 10 miles to spare but I had plans last night so I only had another hour to charge on 14-50 before heading back out. I had enough range, but it would have been nice to pull into a supercharger for 20 minutes and grab another 100 miles.
