How much havok will a 10 mph sign cause on the highway?
None at all. Drivers aren't that stupid, and still maintain enough control over their car to react appropriately.
You, however, might be so stupid that you'd slam on your own brakes to 10 MPH just to make another idiotic point, at which point you get rear-ended by an 18-wheeler who is unlucky enough to be following you. Fortunately, there is only one you, so the gene pool will be thinned out to the point where this situation won't repeat.
