Mine has a precondition option that can both heat the cabin and warm up the battery while still plugged in (a warm battery will give you better range). The heaters keep up, and in fact can warm the cabin faster than on ICE: The latter uses waste heat from the engine, the EV just uses a heating element like a space heater for home would.
Or companies do hire security, but the security team is incompetent and unable/unwilling to adapt to new challenges. Then it devolves into security theater, until either someone new comes who cleans house or a breach happens.
