If there's a confirmed link between neurological disorders and air quality and traffic, wouldn't this show up in major metropolitan cities as well? Someone who lives near a highway is probably exposed to the same if not more automobile pollutants as someone in a city? I guess I'm trying to make the point that if the conclusion that they're drawing (proximity to cars = neurological disorders) it should show up in contexts outside of just "highways."
I think this is a great reminder to make our words on the web more meaningful. If you create something, make sure that the words make sense and are well supported by design, not the other way around.
Worked really well for me. One issue though: after doing a few of these and returning the main page, my uploaded images look broken. Anyway, great job!
