I’ve seen non-steer by wire cars in the ditch because the steering failed. The failure modes for software is different, but things like tie rod ends still break, and the older car the more likely that type of thing is to happen.
Steer-by-wire cars would still have tie-rod ends etc., though. In other words, they have all the same failure modes as purely mechanical steering, plus additional ones introduced by the servos and computers.
And sure, maintenance on old cars is a thing, but every car gets old eventually so there’s not a real difference there.
