Elon Musk likes driving bc he thinks it gives him control. In reality, it just gives you the illusion of control.
When you're driving, your speed is dictated by the speed of the drivers ahead of you. If they're driving slowly, you have to drive slowly.
Your driving is dictated by traffic, the speed of other drivers, closed roads, construction, and other factors you have no control of.
With public transit, you don't have to worry about that. It's all taken care of for you. All you have to do is get to the train on time.
Personally, I feel like I have more freedom when I don't have to worry about traffic, speed limits, drivers ahead of me and behind me, whether I have enough gas in the tank, etc. With public transit, that's taken care of for you.
