CEO Elon Musk is essentially Tesla's PR department, making his X feed a must-read for investors. On Wednesday, he offered updates on Cybertruck production and Tesla's driver-assistance software.

For starters, there was Cybertruck news. Musk effectively killed off the Cybertruck this past week to clear more production capacity for Cybercab, Tesla's purpose-built, two-seat robo-taxi without a steering wheel.

Now, the Cybertruck is getting a little more time. On Wednesday, Musk said production would be extended through the end of summer 2027 to work through more of the order backlog.

"This is not the smartest move from a profit-maximizing standpoint," he added in a subsequent post on X. "But there must be some room in this world for sentimentality, or what's the point?"

The threat to kill the truck may have boosted demand. Tesla didn't respond to a request for comment. The extra production won't change the story of the truck, though. It simply never lived up to expectations. Tesla hoped to produce hundreds of thousands a year. Total Cybertruck production since 2023, however, is in the range of 75,000 vehicles.

The Cybertruck just never really made a dent in the U.S. truck market. It might have been too expensive, too electric, or too oddly shaped. Ford Motor, General Motors, and Stellantis sell some two million full-size pickups per year.

Cybertruck isn't a needle mover for Tesla stock these days. Robo-taxis are. Musk also announced that Tesla's driver-assistance software had been approved for use in Finland.

FSD is the basis for Tesla's self-driving robo-taxi technology. The consumer version requires active driver supervision and is called Tesla Assisted Driving in Finland. It also generates revenue, with more than a million people having paid for the product. European approvals have been relatively slow. Eventually, Tesla is hoping for EU-wide approval by 2027, which would open up a large new market for FSD.

Tesla stock was up 3.6% in midday trading. It's tough to say if FSD in Finland did it. It certainly didn't hurt. The market isn't hurting Tesla stock either, as it continues to recover from fears that the midterm Blue Wave will slow AI growth. The S&P 500 was up 1.6%. The Nasdaq Composite was up 2.3%
