different streets of its own. Potholes are a notorious problem in Los Angeles and frequently cause severe damage to all kinds of vehicles. In 2008, then-mayor Antonio Villaraigosa made "Operation Pothole" one of his top priorities for that year and pledged to fill 1 million potholes. However, due to the city's poorly managed budget, the city's Bureau of Street Services has only a single dedicated pothole-repair truck to cover of streets (meaning that the backlog is still bad and getting worse). Many city streets, such as Wilshire Boulevard, were engineered when cars, trucks, and buses were much smaller, and desperately need to be torn up and rebuilt from scratch to handle the weight of today's larger vehicles. Furthermore, due to its severe budget problems, Los Angeles is one of the few California cities that does not use raised pavement markers on its streets. Thus, Los Angeles drivers must be vigilant not only for potholes, but for other drivers drifting out of lanes due to the lack of tactile feedback normally provided by such markers. On foot In congruence with the assertion of a popular song that "nobody walks in L.A.", only 3.5% of Los Angeles residents commuted to work by walking in 2016 and Los Angeles residents walk for exercise at rates similar to those of other major U.S. cities. There are a number of commercial areas in nearby cities that have been redeveloped in the past two decades specifically to accommodate pedestrian traffic. Old Town Pasadena was redeveloped in the late 1980s by moving parking off Colorado Boulevard so as to make the street pedestrian-focused. Likewise, the Third Street Promenade in Santa Monica was closed off to vehicular traffic altogether in 1965 and revitalized with improved pedestrian amenities in 1988. Downtown Los Angeles has numerous public escalators and skyways, such as the Bunker Hill steps to facilitate pedestrian traffic in the traffic-laden and hilly terrain. Downtown Los Angeles is one of two neighborhoods in Los Angeles ranked as a "walker's paradise" (with walk scores 90 or above) by Walkscore. The other is Mid-City West, which encompasses the area of the city immediately south of West Hollywood and east of Beverly Hills. Nevertheless, much of Los Angeles remains pedestrian unfriendly. A large percentage of sidewalks in the City of Los Angeles (43% or of the ) are in ill repair stemming from the City Council decision in 1973 to use
