The micro-decisions you're referring to are trivial and no more of a cognitive load than deciding where to put your feet while walking. If you're an anxious or unskilled driver, sure, it's probably stressful. But most people reach a point where they are as comfortable driving a car as walking down the street. 30 minutes of driving in my private, climate-controlled car, with a comfortable and highly-adjustable seat, listening to music or podcasts of my choice? And the ability to carry whatever I want? I'd choose that over 30 minutes of sitting on bus or train - which is likely to have uncomfortable seating, too hot or too cold, loud, obnoxious, smelly, or mentally disturbed other people - with no ability to transport anything more than you are willing to carry. Even at par, I would rather have my car - let alone if public transport takes 3x longer. Last time I took BART into SF a guy sat down in the seat in front of me, opened up a plastic bag, and pulled out a needle and started injecting himself with something. I don't believe it was insulin. Uh...rather stick with my car, thanks.
