I understand your point, still I think they could have communicated it properly.I agree with you, but to recycle a post I made in an earlier USS thread:
Imagine that you're in charge of Telsa's operations and you have the following options (assuming that the underlying problem is that USS are in short supply across the industry and can't be obtained):
1) Suspend delivery of all vehicles until you can deliver them as specc'd
2) Deliver cars without and prepare for an expensive retrofit program, using your very low capacity service network (vs ICE vehicles that all visit service centres routinely)
3) Recognise that you were dropping this hardware anyway, so drop it a bit early.
(Note that 2 and 3 are the same result to the customer. You can't have USS if they're physically not available, so you'd have had to have had a car without them in a retrofit scenario.)
You'd be insane not to take option 3, with the offer for anyone who doesn't like it to cancel or defer.
What is the status of this functionality development? What is the roadmap for its release? Will it be even possible without front bumper / headlight camera? Will they retrofit USS if vision park assist isn't good?
Those are questions we should not be speculating, we should get it from tesla with good transparency. If it would be few weeks is one thing, but as many speculated when it was announced there has been few months already and we still don't know anything.
