President Trump has proposed rolling back CAFE standards, the gas mileage levels set for cars and light trucks in the US. Meanwhile, there's a surge of home construction dangerously close to freeways, where air pollutants from car tailpipe emissions contribute to higher rates of asthma, heart attacks, lung cancer and other health risks. If the auto industry is incentivized to keep producing gas-fueled cars, that could mean more cars spewing more air pollutants and greenhouse gases.
