Those 5 California-emission-regulated states have NOT outlawed diesels. You can still buy plenty of diesel trucks & SUVs, even in California. And this PZEV Ford Diesel Car is also allowed, because it's a PZEV. Please stop passing along false info.

You are wrong. Diesel PMs (soot) can get sucked into lungs and cause lung cancer. 100% true.
But gasoline PMs/soot are smaller and FAR more dangerous, because they don't stop at the lung. Gasoline Soot infiltrates the bloodstream and lymph nodes, and causes serious long-term internal damage, like heart disease (source Science News - multiple articles during the last 3 years).
I'd rather breathe Diesel soot than Gasoline soot. Gasoline soot is far more deadly.

ASIDE : I think the whole soot issue is rather silly. You go outside to where farmers or construction workers are plowing the ground, kicking up clouds of dust, and you breathe in several pounds of dirt..... and then turn around and freak out about the 1 gram of Car Soot?!?!? Personally, I'm more concerned about the pounds of farmers/construction dirt I just breathed in.
