Have you tried looking at the new website using the car's built-in browser? The bottom of the home page is cut off, the pages are painfully slow to load (even on WiFi with excellent signal) and not all of the features on the pages work (like elements of the Model S page).
Plus, one of the useful features on the website - clicking on the supercharger map to display charger destinations - that doesn't work using the on-board browser. While you can get much of the destination charger information with the Google maps display, Tesla's website has more information about each of the chargers - plus makes it easy to find stores, service centers and destination chargers, along with information about each location.
