Thanks to the Model S REST API and a little bit of Ruby, my Model S now tweets updates on its charging and driving status. You can follow @PureAmps on twitter if you are extremely bored. All posts to that account are automatically generated using data from the API. Now the first question you may ask is "why would I want my car to tweet"? The short answer is: "you wouldn't". The long answer is that I'm using this as an experiment to get useful data out of the vehicle including daily mileage and energy usage, that I will eventually use to put together some type of web app to track my vehicle's stats.
