I agree on almost everything but the abs bit. Like seatbelts and airbags they should not be necessary, could everyone be trusted to drive perfectly.

But you see, other people that are not, like yourself, perfect drivers do drive in those cars. Hell, they might even drive your car if you're in a temporary state of not-perfect-driveryness.

It's comparable to mouth masks is not about keeping the perfect safe, but to protect the imperfectly healthy (and thereby everybody).
