We already cram so much work into our lives, please don't take my car and make it a workspace as well. Chris Rock does a bit about people with jobs and people with careers. If you enjoy your work and literally take joy from it, why not do it while commuting? That would be amazing for me.
Write poetry while being chauffeured around.
Unlike flagamuffin, I have no desire to ever "retire." Like, no joke... not ever. I want to continue to produce stuff.. .music, writing, businesses, moments with family etc. If you can cut out hours of time in my life that was previously spent mundanely operating a vehicle.... please do.
