In a surprising move, Tesla has announced that it plans to license its Full Self-Driving hardware and software to other electric vehicle manufacturers, adding that the company is already in talks with one other OEM to include FSD technology. Tesla will also allow existing FSD subscriptions to be transferred to new registrations through the end of September 2023.https://www.notebookcheck.net/Tesla-announces-Full-Self-Driving-third-party-licensing-plans-and-confirms-one-time-FSD-subscription-transfer.735287.0.html
It stands to reason that other OEMs would lie to use Tesla FSD because it saves them the cost of R&D. And soon the Feds will mandate v2v and its easier for that life saving technology to implement under one operating system. Say what you want about Tesla FSD, it is not geo-fenced and works pretty good ( I'm in beta FSD).
It really is a no-brainer on letting your FSD subscription to transfer to a new vehicle, it will drive demand on newer Hardware 4&5 vehicles.
