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 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.
