It's been mentioned that once true level 5 FSD is here, Tesla will quit selling cars (or the costs of such cars will be absurdly high) because it will be more economic for Tesla to operate a Robo-taxi fleet instead of selling cars to the public. However, before that happens, do we think Tesla will quit selling FSD paid in full and instead go to a solely subscription based model. Do you guys think that will happen, and if so when? Seems like once FSD gets a wide roll out and can be level 3 or 4 (I forget what the actual levels means), Tesla may decide it makes sense to move to a subscription based model only. Thoughts?
