EV's certainly haven't already won, but I do think there are many cases where they're (almost) perfect. For the person/business who doesn't drive far and can plug it in at home/work, they've now saved a detour to the petrol station. I'd love that. I suspect many businesses that have delivery cars within a city could make that work, assuming all the other costs lined up. I think making batteries portable is very possible, but it'll take a generation or three to get that right, assuming the above market segments are saturated and Tesla sales are limited by this issue. What remains a problem for me are the lifetime of batteries, and the need to drive outside of coverage areas. I like to drive cars for a while rather than replace them often, so don't like the idea of replacing a large part of the cost. And I don't want to worry about charging stations when going on holiday. But again, for a city-based business that replaces cars more quickly than the batteries would last, those issues might not be relevant. One strong driver for innovation is that battery technology would become important to (at least) both the IT and auto industries. Research and innovation would accelerate and be useful to both industries via cross-pollination.
