I want to find a reason to be angry/upset by this but I find I really can't justify ever needing or wanting to drive that fast. The best I can think of is that it won't be very effective at curbing speeding related fatalities. Besides the mostly obvious fact that vehical speed likely follows a bellish shape centered at/near the limit, so most accidents involving speeding will statistically still be near the limit which in most places is well under 112 MPH.
