Texas has authorized 45 Cybercabs for a Tesla line built to make 125,000 a year

Forty-five cars cleared for driverless work in Texas ^[3], set against a Cybercab line at Gigafactory Texas that, per Tesla's installed-capacity table as reported by The Motley Fool, is rated above 125,000 vehicles a year and already producing ^[4], works out to 0.036 percent of a year's rated output ^[19], or roughly three hours of it at an even daily rate ^[20], which is a useful way of saying the building is not the thing in the way.

Tesla says the packs are ^[15]. The letter that says so also puts 4680 cell output behind three ramps at once ^[16], and it gives neither a pack size for the two-seater nor an output figure for the cells ^[22], so the constraint is named without being measured, and nobody outside the company can turn cells into cars on the back of an envelope.

Which makes the price the more interesting document. At about $376 a share and roughly 155 times what Tesla is expected to earn next year ^[23][14], the multiple implies something near $2.43 of earnings per share in that year ^[21]; Thursday's 5.7 percent move marked the stock up from about $356 ^[24] ahead of an event whose passenger list was five sweepstakes winners drawn at random ^[8].

Three readings survive that evidence. In the first, packs bind, authorizations creep up in dozens, and the first-quarter promise that the Cybercab would begin replacing the Model Y fleet and become the largest-volume vehicle in it ^[13] stays a sentence in a letter. In the second, the real gate is permission and driverless validation rather than cells, 45 is a number Tesla chose, and cell output tells you little about 2027, though it was Tesla, not an outside critic, that put packs at the front of the queue ^[15]. In the third, Tesla feeds the cells it has to the robotaxi, trading Model Ys it sells outright for cars it rents by the ride ^[16].

I read the July disclosure as the load-bearing one and the launch as the smaller event. The first-quarter update had the Cybercab on schedule for volume production starting in 2026 ^[11]; the July 22 update keeps production dates for the Semi and Megapack 3, drops the word volume, deletes the Cybercab from the sentence altogether, and stops promising volume production of Optimus as well ^[12][10]. Nothing on Thursday replaced the date, not a rate and not a timeline ^[9]. Or rather, the narrower version of that claim is the sturdier one: a vehicle that was a concept in October 2024 ^[6] and entered production earlier this year according to Tesla's latest quarterly filing ^[5] has cleared everything except volume, and volume is the only part that pays.

What would prove this wrong is cheap to check. A published Cybercab production rate, or an authorized fleet in the thousands with no new pack capacity behind it, would mean the July language was describing some other bottleneck than the one holding the robotaxi where it is.
