The fleet-data moat is real but not automatically permanent
The moat depends on continued unsupervised expansion, safety performance, regulatory acceptance, and superiority versus competing architectures. Every one of those is a condition, and none is settled. Treating fleet data as a standing advantage rather than a contingent one is the consensus error this seat exists to attack.
Double-counting risk — the central objection
Vehicles, FSD, robotaxi, Optimus and compute share common assets and assumptions. Their values cannot be modelled as fully independent options.
A single technical or regulatory failure can reduce several segments simultaneously. A sum-of-the-parts that adds five independently-valued segments is therefore not conservative — it is structurally optimistic, and the more segments you add the wronger it gets.
Capex operating leverage cuts both ways
Heavy investment could create later operating leverage. Current evidence shows near-term margin and cash-flow pressure. The model must test both productive investment and prolonged capital intensity, rather than assuming the first because the second is uncomfortable.
One quarter is not a trend — but it is not nothing
Q2 should not be treated as proof of permanent decline. It should still update probabilities, because it confirmed two things happening at once: margin compression and rising capital intensity. A single quarter that confirms a mechanism is worth more than a single quarter that merely moves a number.
Dissenter recommendation
Force explicit probability weights and map shared dependencies before assigning any optionality value. No segment gets a number until the correlations between segments are written down.
