Connected cars are great—at least until some company leaves unencrypted location data on the Internet for anyone to find. That's what happened with over 800,000 EVs manufactured by the Volkswagen Group, after Cariad, an automative software company that handles much of the development tasks for VW, left several terabytes of data unprotected on Amazon's cloud.

According to Motor1, a whistleblower gave German publication Der Spiegel and hacking collective Chaos Computer Club a heads-up about the misconfiguration. Der Spiegel and CCC then spent some time sifting through the data, with which allowed them to tie individual cars to their owners.

"The security hole allowed the publication to track the location of two German politicians with alarming precision, with the data placing a member of the German Defense Committee at his father’s retirement home and at the country’s military barracks," wrote Motor1.

Apparently Hertz's purging of electric vehicles from its fleet isn't going fast enough for the car rental giant. A Reddit user posted an offer they received from Hertz to buy the 2023 Tesla Model 3 they had been renting for $17,913.

Hertz originally went strong into EVs, announcing a plan to buy 100,000 Model 3s for its fleet by the end of 2021, but 16 months later had acquired only half that amount. The company found that repair costs—especially for Teslas, which averaged 20 percent more than other EVs—were cutting into its profit margins. Customer demand was also not what Hertz had hoped for; last January, it announced plans to sell off 20,000 EVs.

Asking its customers if they want to purchase their rentals isn't a new strategy for Hertz. "By connecting our rental customers who opt into our emails to our sales channels, we're not only building awareness of the fact that we sell cars but also offering a unique opportunity to someone who may be in the market for the same car they have on rent," Hertz communications director Jamie Line told The Verge.

The 2020s have been quite the decade so far. No matter what insanity has transpired by a particular December 31, the following year has shown up and promptly said, "Hold my beer."
