Governments force automakers to install features all the time, from ABS to three-point seatbelts, airbags, child-proof door locks, emissions standards, etc; drivers are required to use snow-tires or install chains in many jurisdictions, others require safety-kits, spare tires, high-vis vests, etc. Considering four-wheel drive is a safety advantage, it’s pretty far from outlandish to imagine a government requiring it on new cars sold sometime in the future, just like any-lock brakes went from an add-on feature to requirement in many jurisdictions. We already live in the world you so fear, and it seems automakers have survived just fine.
