RWD doesn't change braking (primary cause of understeer in winter, unless you enjoy accelerating in corners on ice) and actually lends you more control in oversteer scenarios. Correcting oversteer in an FWD car is harder.
You have to actively be trying to do something stupid if RWD gets you in trouble in a car with ESP and proper winter tires.
AWD that actually drives both axles all the time is even better, but it seems EVs often tend to switch one motor off when they can anyway.
