We're way off topic here, but briefly, though I'm not sure, I THINK it was probably the widespread availability of natural gas for home use. Early coal furnaces had to be fed by hand. Later, automatic screw-drive stokers were available for home heating, but I seem to recall reading that they weren't 100% reliable. Being able to set the thermostat and let the gas provide the heat was a huge convenience that coal just couldn't match. Some places where coal was extraordinarily cheap continued to use coal widely well into the late 20th century. In the early 1990s, I spent some time in Northeast Pennsylvania. On cold winter mornings, my eyes would smart from all the sulfur pollution in the air. To apply this to EVs, I think the tipping point for their sales will come if and when gasoline and Diesel fuel are not just expensive, but inconvenient to get.
