I'm generally strongly in favor of technical system for making speeding impossible -- for example I don't think it should be legal to sell cars that are able to go 100km/h on city streets. But this implementation seems designed to elicit backlash. Beeping is bad, and setting the tolerance at zero is not friendly given general driver behavior. I'd find it much more sensible to have "smooth" systems, such as a constant "buzzing" sound whose volume increases with the square of the speed excess, or translating pedal pressure into speed in such a way that convexly increasing amounts of pressure are required to go further above the limit.
