Personally I don’t think that many people are dumb enough to doubt Tesla will eventually get there with FSD. You can doubt the timeline, sure, but there’s literally no precedent to doubt Elon and team eventually reaching the goal.
What’s actually missing for the market when it comes to FSD is some hint of the details that they can understand, so they can start to model what Tesla is actually going to do with FSD. This is why market tends to feel more “comfortable“ with Cruise or Waymo…they see the branded goofy vehicles driving around, they’ve seen the customer-facing interface/app, seen hints of the marketing strategies they’re used to, etc. It has very little to do with how “good” those robotaxis are relative to human drivers, but there’s something tangible that gives analysts etc. something to grasp. Everyone knows the technology/driving will eventually get there, but when it does, what does the whole thing look like?
With Tesla, the concrete direction is unknown, only the vast array of possibilities, that span from familiar (Uber without drivers, a la Cruise and Waymo) to pretty wild and disruptive (shared cars, owner fleets, no more Teslas sold to customers). As the likely first to real FSD, Tesla chooses which way the whole thing goes. If you’re Wall St., how could you even begin to model the economics when you feel there isn’t enough of a hint of Tesla’s intended business model? This is why I believe the market is awaiting hints of intention….the existence of a ride-hailing app, or some parameters that might govern licensing to other OEMs, or what an owner fleet would look like. Really, anything official that makes it real and can be modeled.
Otherwise, Wall St is left with one of two conclusions: Either none of those details have been fleshed out yet or decided because Elon finds them trivial details relative to the challenge of actually solving FSD, or they have been worked out and are completely and totally under wraps. Either way it forces you to ignore FSD [as anything more than an expensive ADAS option] for the time-being.
(Note this is in contrast to how Tesla bulls look at it: all possibilities are intriguing based on loose modeling and Tesla will ultimately choose what makes the most sense, both from a mission and business perspective)
