The posted speed limit is some information, but more important are things like size of the lanes, visibility, amount of other traffic, separation from the other direction of traffic, separation from non motorized road users, curves in the road, pavement condition, etc.
If US-101 in Sunnyvale were posted for 45 mph, that wouldn't be a reasonable and prudent limit; it's got lots of separation and wide lanes, and the pavement is ok -- traffic permitting, you can travel at high speeds. If it were posted at 80 mph, it wouldn't be reasonable and prudent either -- the pavement isn't that great (unless it was repaved recently), most cars would be bumping around too much at that speed.
Moreover, I don't know who would purchase a car that promised to strictly follow posted speed limits, when they have alternatives.
