The World's Top Car-Owning Countries

The United States is often criticized for its perceived nonchalance toward air pollution despite persistent statements to the contrary by the current presidential administration. The US remains the number one contributor globally to harmful chemicals in the air, with the fossil-fuel consuming transportation industry being a primary emission source. With more than 250 million vehicles on US roads, the US surpasses even China based on total vehicles in use despite China's much larger population... at least for now. China has already surpassed the US in annual new car sales.
