Your discussion of batteries is spot on. Battery prices dropping will drive a lot of innovation. But your article touches on what I think is even more compelling. When people compare the cost of gas cars to electric cars, they envision electric cars the size, shape, and function of gas cars. They envision cars like Teslas. You mention vehicles whose wheels can be retracted, park sideways, and drive in micro-mobility lanes protected from large vehicles, as well as delivery bots toting e-commerce packages. The cost analysis in these situations is completely different because we are talking about different vehicles doing different jobs than vehicles today. The total cost of ownership for these vehicles can be less than gas-powered cars even if battery prices stayed the same, which they won't. To me, that is the most exciting aspect of the transformation of mobility we are experiencing.
