Tesla and even EVs in general with battery thermal management (that is pretty much everyone each Nissan LEAF in USA) are working just fine under extreme conditions (cold / hot). Sure the temperature does affect battery range as much as 50%, but you can recuperate some of that via pre-conditioning - that is to warm the batteries to improve the chemistry. I drive an EV myself and living in Northern NJ, temperatures can go below lower teens in some years. After a 30 minutes pre-conditioning, batteries get warmed up to 42F, which would certainly alleviate the range issue. Additionally, ICE cars also suffer on range under cold conditions.
