What about reuse of batteries for grid storage? Weight/capacity ratio doesn't matter for something sitting on the ground. I presume that with economics of solar you could use even almost-dead batteries profitably. ---- EVs are still better than ICE cars, so don't take any EV problems as an excuse to keep producing ICE cars. E.g. even if the grid was entirely oil-powered, large plants burn oil more efficiently and cleanly than ICE, and keep emissions away from cities. But cars as a form factor are still inherently inefficient for moving people. It doesn't matter if they're electric, taxis, or self-driving: compared to trains they have low road throughput, depend on tires with much higher rolling resistance, and particles from tire wear are another source of pollution.
