Earlier quoted context omitted.
There's nothing mysterious about them. Car companies are required to produce clean vehicles, or they can instead buy credits from companies who do. Companies are paying right now rather than producing, and Tesla is there to benefit from it. There's nothing shady or mysterious here.
Pretty odd to consider that every other carmaker, obsessed with optimizing their business, would rather pay Tesla straight cash than rush out an electric drivetrain car. Across the Taycan, i3, and Bolt, there’s certainly plenty of evidence that they can.
The dealers also have an inverse incentive to sell them so one has to go way out of their way to purchase an electric from the legacy manufacturers. It's a classic disruption case against entrenched players who refuse to adapt. The only one making a real effort is VW and they're currently paying dearly for it.
