I think emissions -- or, more correctly, the cost of getting engines certified for use in the USA -- is a big factor keeping clean diesels out of the country. Like this one:

Or this one:

Safety by itself probably isn't a big factor in MPG...but the concept of 'safety over everything' is one of those ideas that keeps people buying SUVs because they think they're 'safer'.
