My car, which is 14 years old, doesn't have such a feature. Despite that
my GPS navigator manages to display the speed limit, except in places
where reception from satellites is blocked. I assume that the limits are
contained in map data. Why then would the car need to read roadside signs?

OK, I'll concede that there are sometimes temporary limits in place
because of roadworks and so on, but that's the exceptional case.
