When I worked with Toyota
When I worked with Toyota they would carefully listen to you, but they did not seem to really trust anything that was not done by them in their traditional way. They had lots of specific rules and a strict hierarchy to follow. Tesla is objective and product goal oriented, there is no tradition component in their engineering processes. So it is easy to see how Tesla and Toyota would fundamentally disagree and separate quickly. It is interesting that Toyota did not build a BEV after producing the RAV4 EV with Tesla.
