It's interesting to try to work out what the civ-style "dependency tree" of viable electric cars has been. It requires at the bare minimum high energy density light batteries, which were a spinoff of the cellphone revolution. As well as high efficiency digital power control, which while not impossible in 1970 would have been larger and heavier without modern SiC semiconductors.
Solar panels are an even more remarkable example of compounding a thousand different 1% improvements.
