Reuters says it's still unclear exactly whether Apple will even sell its own branded car at all or do something else in the space, like sell the software components.
Many acolytes of the two brands still hoped they would have combined. Tesla and Apple both have strong brand affinity as innovators who have disrupted in their respective spaces, but the latter has one thing Tesla does not: operational excellence.
Automotive offers a lot of monetary potential as the industry continues its monumental shift to electric and self-driving technology, areas where tech companies have a lot to offer. Apple is skilled in squeezing efficiency out of batteries through deep hardware and software integrations, and it has also introduced advanced LiDAR sensors in its iOS devices, a technology present in most emerging self-driving implementations (except Tesla's, notably).
