Are you including the combined local, state, and federal subsidies for roadways? Are you considering the implicit subsidies to automobile infrastructure such as "free" curbside parking, and the ones that are offloaded onto the private sector, such as mandatory minimum parking requirements. Or zoning and urban planning that explicitly seek to structure society around cars. Glad you mentioned the externalities of pollution that people are allowed to create without penalty, but are you also considering that CO2 is hardly the only thing to worry about. Air pollution is a major cause of neurological illnesses, since auto exhaust is neurotoxic, as is non-exhaust pollution from brake pads and tires.
