Researchers at the Harvard School of Public Health found that pre-natal exposure to pollution is correlated with higher rates of autism. As you can imagine, most pollution that people deal with on a daily basis comes from cars. Now that the whole anti-vaccine pseudoscience has been thoroughly debunked (over and over and over), I'm looking forward to those same folks taking their zeal and their resources into the fight against car pollution. Because it's all about protecting kids, right?
