What Happened: The update -- said to be version 11 -- is likely to arrive near the holidays, according to Electrek.Twitter user Green, who reports on developments surrounding code, said that it appears as if "there's going to be a livestreaming of car videos to the phone app."The code sleuth said that a single camera on the vehicle streams at up to 30 megabytes per minute, which according to the expert, would not take too much bandwidth for periodic checks of the camera's feed.In response to when the new feature might be released, Green said it seems to be in the "wings."> Well, the remote camera viewing seems to be in the wings, whenever they'll drop it in 2020.48 or if they'll postpone it again - I don't know.> > -- green (@greentheonly) November 27, 2020Elon Musk, CEO of Tesla, hinted at a "hot" software feature release during the holidays on Twitter this month.Why It Matters: Users may have to pay for a premium data subscription due to high data usage involved in live streaming, Engadget reported.

Wall Street is bracing for Tesla Inc's (NASDAQ: TSLA) arrival to the S&P 500 Index on Dec. 18.What Happened: The addition of the California-based automaker is expected to create challenges because of the company's size, $555 billion, and volatility. Tesla's share price jumped 40% right after the S&P 500 announcement on Nov. 16, and the addition comes at a time of pandemic-related volatility, the Wall Street Journal reports. Tesla is the biggest company to ever join the index, and it'll be the sixth largest by market capitalization. Elon Musk's company might put $100 billion "in motion" when added, as funds try to sell other companies' stock to buy Tesla's, according to WSJ.To help ease the potential trading chaos, some Wall Street managers recommend splitting the addition "over two trading days," something that has never happened before, WSJ notes.Ben Inker, who manages asset allocation at investment manager GMO believes any unpreparedness might have consequences. "The people who will pay the price if S&P screws up are the investors in passive S&P," he says.Why It Matters: Tesla's addition to the S&P 500 also happens the same day the so-called "quadruple witching" takes place. Every last Friday of the quarter marks the day when futures and options expire at the same time, which increases the volume.This, investors say, might help with the liquidity that day but may also increase market volatility. Price Action: Tesla shares traded 0.17% lower at $584.77 in the after-hours markets on Friday.Photo courtesy of UnsplashSee more from Benzinga * Click here for options trades from Benzinga * Guggenheim Fund Mulls Investment in Grayscale Bitcoin Trust * Bloomberg Releases Its 2020 List Of Wealthiest Families In Asia(C) 2020 Benzinga.com.

Skeleton Technologies is not a publicly traded company, but it's one to keep an eye on as it traverses territory partly claimed by Tesla Inc (NASDAQ: TSLA).Next-Gen Battery Business: The Estonian maker of ultracapacitors, also called supercapacitors, completed a Series D round of funding this month, raising $48.1 million. It raised a combined $38.7 million in earlier rounds. The company was founded in 2009 and counts the European Investment Bank among its investors.The company's website lists as competitors: St. Louis-based EaglePicher Technologies; Pennsylvania-based C&D Technologies; Germany-based IBC Solar; and, tantalizingly, Maxwell Technologies, which was bought by Tesla in 2019.Maxwell also makes ultracapacitors, which hold the promise of delivering much greater energy density than batteries. This translates into longer driving ranges and faster charging times for electric vehicles.Skeleton announced in October it had struck a deal with Wrightbus, a Northern Irish maker of buses power by hydrogen fuel cells.In September, it announced that it is working with the Karlsruhe Institute of Technology in Germany to develop a "SuperBattery." The company says this will use a "curved" form of the wonder-material graphene to combine the fast-charging qualities of supercapacitors with the storage capacity of batteries.IPO Hints: When the company hired Wolfgang Breme as its new CFO last year, it touted the executive's IPO experience:"His extensive experience at Aixtron, a TecDAXcompany with a market cap north of 1 billion euros, is an asset to Skeleton Technologies, with the rapidly growing ultracapacitor market providing an opportunity for a public listing in three to five years' time."Alternately, Maxwell's experience with Tesla raises the possibility that Skeleton could be acquisition target of an EV maker as well.Photo courtesy Skeleton TechnologiesSee more from Benzinga * Click here for options trades from Benzinga * New PlayStation No-Nos: Profane Tweets, Rogue PS Plus Collection Deals, Scammer eBay Photos * Former Zappos CEO Tony Hsieh Dies At 46(C) 2020 Benzinga.com.
