Honestly, that's a bad idea. The layoffs would be insane at Tesla. For one thing, neither company is all that good at actually building cars.I don't know what Apple wants in the car business but this might be a good time to think about buying someone else to move forward more quickly. With the purchase of Tesla, they would provide the financial backing Tesla needs to continue. They would want to remain hands off for a few years to allow the company to continue as is but partner on technology to learn and at some point combine. Shareholders should ask that Tesla focus on quality and on getting full autonomy to the existing fleet sooner than later, they are already delayed to the point some original buyers are ready to trade cars without ever using the feature they paid for. Some of the early buyers paid 2 years ago. In this bracket of cars, many owners are ready for another new car.
Apple would be better off making an exclusive contract with Honda or Toyota, who actually have the ability to make quality cars for an affordable price. Infused with Apple's technology, you take the poor Tesla build quality out of the equation.
