I am kind of curious what the vision system does when the sign has different speeds for different classes of vehicle. Or signs for night vs day.

Or on various Seattle roads, like I-5 where the speed limit is variable not just by time of day and congestion, but even which lane you're in. (Not to mention that the signs over each lane don't show the standard white rectangle with black text.)
