Just to add to this, though I'm obviously in agreement with you, is that most engines (gas or electric) used in US cars barely distinguish between 23 MPH and 39 MPH. You could probably just push your foot down a tad bit harder on the gas pedal and make up the speed differential. That's fine; many previous limitations on speed were based around actual deficiencies in automotive development (heavy car bodies, lack of synchros when shifting, heavy clutches, etc) but now that consumer vehicles can so effortlessly go from "0-60 mph" (the common metric used to judge acceleration of cars), it's harder than ever to educate folks on the effects of their speed.
