Some modern vehicles activate the cornering light on one or the other side when the steering wheel input reaches a predetermined angle in that direction, regardless of whether a turn signal has been activated. For legal purpose, motor vehicles are often identified within a number of vehicle classes including cars, buses, motorcycles, off-road vehicles, light trucks and regular trucks. Alfasud boxer engine (1,500cc, 95 HP) combined with a three-phase asynchronous electric motor (16 HP, 6.1 kgm of torque) supplied by Ansaldo of Genoa. URR was pressing to convert many of its cable lines to overhead electric traction, but this was met with resistance from opponents who objected to what they saw as ugly overhead lines on the major thoroughfares of the city center. The city purchased and reopened the lines in January 1952, but another referendum that would have funded maintenance for the California Street tracks and the powerhouse and car barn at Hyde and California failed in November 1953. The amendment to the city charter did not protect the newly acquired Cal Cable lines, and the city proceeded with plans to replace them with buses; in addition, businesses in Union Square and downtown began advancing plans to convert O'Farrell to automobile traffic, which would remove service through the Tenderloin district via the inner section of the O'Farrell Jones & Hyde line.
One of them was the O'Farrell-Jones-Hyde line, the Hyde section of which still remains in operation as part of the current Powell-Hyde line. The result was a compromise that formed the current system: the California Street line from Cal Cable, the Powell-Mason line already in municipal ownership, and a third hybrid line formed by grafting the Hyde Street section of Cal Cable's O'Farrell-Jones-Hyde line onto a truncated Powell-Washington-Jackson line, now known as the Powell-Hyde line. In the 70’s we endured the sonic horrors of automotive 8-track, click-click and all, then cassettes and now these luxury, almost custom engineered systems. In the 1920s and 1930s, these remaining lines came under pressure from the much-improved motor buses of the era, which could now climb steeper hills than the electric streetcar. Each section supplies pressure to one circuit. 10 m/s has 100 times as much energy as one of the same mass moving at 1 m/s, and consequently the theoretical braking distance, when braking at the traction limit, is up to 100 times as long. The Powell-Mason line is still operated on the same route today; their other route was the Powell-Washington-Jackson line, stretches of which are used by today's Powell-Hyde line. This company's first line was on California Street, and is the oldest cable car line still in operation.
In 1880, the Geary Street, Park & Ocean Railway began operation. By the beginning of 1906 many of San Francisco's remaining cable cars were under the control of the United Railroads of San Francisco (URR), although Cal Cable and the Geary Street Company remained independent. Despite the changes, much of the systems infrastructure remained unchanged from the time of the earthquake. The line started regular service on September 1, 1873, and its success led it to become the template for other cable car transit systems. In response, a joint meeting of 27 women's civic groups, led by Friedel Klussmann, formed the Citizens' Committee to Save the Cable Cars. This passed overwhelmingly, by 166,989 votes to 51,457. Klussman led another campaign in 1948 to have the city acquire Cal Cable, but the referendum fell short of the required 2⁄3 majority, with 58% in favor of acquisition; a second referendum in 1949, requiring a simple majority, passed and the city began negotiations with Cal Cable.
In August 1951, the three Cal Cable lines were shut down when the company was unable to afford insurance. For its initial three cables, the Ferries & Cliff House Railway constructed a three-story structure to house two 450 horsepower (340 kW) coal-burning steam engines. By 1944, five of those cable car lines had survived: the two Powell Street lines - by then under municipal ownership, as part of Muni - and the three lines owned by the still-independent Cal Cable. In 1878, Leland Stanford opened his California Street Cable Railroad (Cal Cable). The quake and resulting fire destroyed the power houses and car barns of both the Cal Cable and the URR's Powell Street lines, together with the 117 cable cars stored within them. The following year the California Street Cable Railroad opened two new lines, these being the last entirely new cable car lines built in the city. In a famous battle of wills, the citizens' committee eventually forced a referendum on an amendment to the city charter, compelling the city to continue operating the Powell Street lines. With the reduction in the number of cable car lines, the single 750-horsepower electric motor was eventually able to take over the job of running all of the lines.
