They are probably of little concern to people who decide these issues..
Most cities HAD pretty decent public transportation until the auto/tire/asphalt/etc lobbyists "took care of them".

How General Motors Deliberately Destroyed Public Transit
by Bradford Snell
The electric streetcar, contrary to Van Wilkin's incredible naïve whitewash, did not die a natural death: General Motors killed it. GM killed it by employing a host of anti-competitive devices which, like National City Lines, debased rail transit and promoted auto sales. This is not about a "plot" hatch by wild-eyed corporate rogues, but rather about a consummate business strategy crafted by Alfred P. Sloan, Jr., the MIT-trained genius behind General Motors, to expand auto sales and maximize profits by eliminating streetcars. In 1922, according to GM's own files, Sloan established a special unit within the corporation which was charged, among other things, with the task of replacing America's electric railways with cars, trucks and buses.
A year earlier, in 1921, GM lost $65 million, leading Sloan to conclude that the auto market was saturated, that those who desired cars already owned them, and that the only way to increase GM's sales and restore its profitability was by eliminating its principal rival: electric railways. At the time, 90 percent of all trips were by rail, chiefly electric rail; only one in 10 Americans owned an automobile. There were 1,200 separate electric street and interurban railways, a thriving and profitable industry with 44,000 miles of track, 300,000 employees, 15 billion annual passengers, and $1 billion in income. Virtually every city and town in America of more than 2,500 people had its own electric rail system.
General Motors sought to reduce competition from electric railways through a variety of measures, including the use of freight leverage. GM, for decades, was the nation's largest shipper of freight over railroads, which controlled some of America's most extensive railways. By wielding freight traffic as a club, GM persuaded railroads to abandon their electric rail subsidiaries. With a pack of notorious mobsters, GM helped purchase and scrap the street railways serving Minneapolis-St. Paul.
Members of GM's special unit went to, among others, the Southern Pacific, owner of Los Angeles' Pacific Electric, the world's largest interurban, with 1,500 miles of track, reaching 75 miles from San Bernardino, north to San Fernando, and south to Santa Ana; the New York Central, owner of the New York State Railways, 600 miles of street railways and interurban lines in upstate New York; and the New Haven, owner of 1,500 miles of trolley lines in New York, Connecticut, Rhode Island and Massachusetts.
