This YouTube Video of Tesla press conference differs from the Vimeo video of the same press conference. This video is 19 minutes in length and includes an introduction by V.P Reyes as well as a Q&A period after V.P. Rawlinson's presentation not seen in the Vimeo. The camera angle also better displays the background video of Model S Alpha traversing some back roads.
