And no, the Cadillac ELR is not a Model S competitor as it fails in every area that matters, which is why the ELR is selling in such miniscule numbers.
Why do people continue to make this statement? EVERY car developed that carries some sort of "electric=miles" design is a competitor of Tesla. THAT is why Musk wanted to release the patents...he needs the competition, in any form, to step and start developing systems that require the needed network for use...in his case the Supercharger stations..in others, gas stations with available charging stations as well. I imagine that Musk realized that he cannot do it all by himself and he actually needs the industry to adopt a standard so that unbridled development would occur within the hybrid, BEV, EREV, etc. industries. If not, his plan for a greener automotive nation will not be reality for many, many decades.
