Majority of consumers dont really care fossil fuel destroying the biosphere. They care only affordability. The vast majority car purchases are non-EV...and maybe at best hybrid. Currently EVs sales have stagnant and Tesla had to subsidized it partially via 7K credit and free charge. I dont see as a way going forward unless Tesla type of car can drop to under 10K in 2nd hand market and motorshop repair able to service it. Toyota still outsell and outvolume Tesla by several fold and still growing with recalls near miniscule unlike how many times Tesla doing recalls this year alone.

You can. You'll need a tank and a pump and a company that will deliver. It's more commonly done (that I've seen) with diesel for farms, but I've come across people who do it for gasoline also. From what I understand, they can get a better price per gallon. I'm sure there's some laws and regulations around it but it is certainly feasible. At least in the USA.

Yeah, I call BS on "they are awful in the snow". I live in Colorado, and have spent 40 years driving Subarus and Audi Quattros. My Tesla Model S is at least as capable in the snow as those. I attribute much of that to having two independent motors so it doesn't have to play any tricks with center differentials or torsen availability. Though I will admit that my B6 Audi S4 with Blizzaks and traction control off was a lot of fun in the snow.

heavier isn't perfectly good thing. One of another reason is that heating on ICE is free while on EV is expensive

They probably meant they are awful in cold weather because the cabin heater uses up 20% to 33% of the battery capacity. Newer EVs have swapped out resistive heaters for heat pumps, which helps a lot.
