So, go to www.tesla.com/build/models and hit the "X" in the browser to stop loading (PC/iPad - not sure with Mac) about halfway through bringing up the page. If you don't time it right, it will just go to the regular design studio. However, if you time it correctly, you'll get a new variant of the design studio (perhaps in advance of the III configurator) that bundles their offerings into various packages. Clearly, Tesla is trying to lead the end user to certain "templates" that ease production and speed delivery time over full customization that notes "will delay delivery time". Interesting, no?
