“Although the motorcar was the quintessential private instrument, its owners had to operate it over public spaces...One solution...was to rely on general taxation to support private transportation...The basic thrust for street improvement came less from idealism than from special interest, however. By the 1920s, a coalition of private-pressure groups, including tire manufacturers and deals, parts suppliers, oil companies, service-station owners, road builders, and land developers were lobbying for new streets...they justified public financing for such projects on the theory that roadway improvements would pay for themselves by increasing property-tax revenues along the route.” (163-64)
