While speaking with the Nikkei (sub. req.), a Japanese news outlet, Musk revealed the automakers intentions:
Striking a single deal with one automaker, like Tesla did with Toyota, is one thing; licensing technology to numerous manufacturers could seriously increase Tesla's clout in the industry....Tesla has already contacted tie-up partners Toyota and Daimler AG and asked them if they are interested in licensing its technologies.Tesla is also interested in joining hands with Toyota in the area of customer service, adding that Tesla's cars could be serviced at Toyota facilities.
