Oh, they probably haven't driven on city streets either. With America's crumbling infrastructure. city streets are pothole-ridden messes, with traffic-calming, school buses, bike lanes, and other interesting twists; and unpredictable traffic including cyclists darting between motorized vehicles. Not only is it unpredictable, but it changes day-to-day - with construction, schools being in or out of session, and any of the other obstacles that the city likes to throw in drivers' way.
The people who come up with this crap are those who will benefit from it financially if/when idiot-lawmakers allocate money to it. The real solution is funding planned infrastructure renewal and intelligent traffic planning and control. Butt that is hard, unsexy, actual work that requires real engineers - not political appointees and tenured "seniority" employees.
