Diesels are, however, very fuel efficient and can last a long time. But they give off small particulate matter that gets lodged into people's lungs, shaving days, months and years off people's lives. I don't know how clean clean diesel cars are, but every time I see black soot coming out of a truck, I want to punch someone. That's going straight into our lungs.

Point is, even a gasoline suv pollutes less than a prius overall if you don't use it that often.

Just arguing that as an engineer, you should look at other solutions instead of jumping the bandwagon. Let pointy hairy bosses and ruby on rails guys do it instead.
