Oh, please. I'm near eighty years old, and I'm quite confident I'll be able to back up looking over my shoulder with my hand on the yoke, and not kill myself or others around me. It might even be easier than using the round wheel. Humans have been adapting to all sorts of things for centuries, and it has generally been NO BIG DEAL. Several who have tried it have reported it working well, yet there are naysayers who have never tried it who are convinced that it can never work as well as the small diameter plastic wheel they grew up with. I remember watching the bus driver as he drove us school kids to class with his steering wheel LAYING DOWN!!! How in the world did he ever get us to school? And did any of you concerned folk ever try driving a 60-ton tank? NO round steering wheel there, my friends, yet the drivers, not yet twenty years old, learned how to maneuver those behemoths backwards into the trees for cover.
You folk who are hesitant, please contribute a few thousand to my fund so I can buy a new Model S, and I'll do a month or so of test drives and report back. I prefer blue, thank you.
