I don't get this idea that they want to make a car. Their products tend to be very personal - an music player, a desktop/laptop that you become very attached to, a smart phone that keeps you in touch. They also tend to create products only when they believe they can do it better than anyone else and the electric self-driving car market has hardly begun let alone gelled into something they can disrupt.
I love my car but if I wasn't driving for ride-share right now to make ends meet it would sit the two days I'm off every week. I just don't have the same relationship with it that I do my Apple products.
The car Apple wants to make is what is going to be your demise as a ride share driver on the weekends. The delivery space is also a huge one for groceries etc. Amazon just made. a huge investment in Rivian. The electric car and machine learning businesses along with semiconductor firms are likely to have the largest areas of growth in the next decade.
Amazon is aiming to cut it's carbon footprint in half by the year 2030 using such electric vehicles. You of all people being in the ride sharing game should know this. Have you not got the message that Uber's ultimate goal is to not need your services ASAP?
