At least in the US, vapor recovery seems to be implemented differently by state. In California I notice fumes when pumping gas far less than in New York. There seems to be various types of nozzles and legislation (some with rubber boots and some without). Since 2006 cars were apparently required to have vapor recovery systems built in, so the EPA has dropped requirements for systems at the pump. California (not surprisingly) still seems to lead the way in improving the effectiveness of the systems despite the EPA backing off.
Yea I was just thinking the other day how I haven’t actually smelled gas in a long time. I used to love the smell as a kid, but I’m happy it doesn’t seem like my children will get the same exposure.
