I've been in the USA many times and don't see many private saloon car turbo diesels..why? Is it memories of noisy slow diesels from the 70s/80s?
Untrue - we could have both - high gas mileage AND pollution control.
Heart Disease and Diesel Exhaust (PDF)
Diesel particles are the tiniest of deadly combustion particles. Recent medical investigations suggest that their extremely small size may allow them to pass easily into the bloodstream where they can cause oxidative stress and inflammation that leads to heart disease and premature death.1
...Medical Studies Link Diesel Particles to Cardiovascular Disease and Death.
• Exposures to particles are associated with elevated risk of premature cardiac death as documented in the two largest air pollution studies ever conducted.4
Daily exposures to particles are also linked to premature death in the 90-city National Morbidity and Mortality Air Pollution Study5
• Workers in the trucking industry have a 32-49% higher risk of heart disease than the general U.S. population according to a 2007 study.6
• A link between exposure to particles and vascular inflammation/atherosclerosis has been found in animal studies and could explain how particles are linked to heart attacks.7
• Ultrafine particles—as concentrated in fresh diesel exhaust --lead to systemic acute inflammation and exacerbation of cardiovascular disease and atherosclerosis according to recent studies.8,9
• Traffic proximity is related to heart attacks and mortality 10,11,12
A 2007 study of 700 heart attack survivors shows that they were most likely to have been in heavy traffic the hour before they suffered the heart attack, whether in cars, streetcars or buses. Studies find that traffic-related health risks are better correlated to truck rather than car volume and therefore may be more strongly related to diesel engine exhaust.
• Particles elevate cardiac risk for women.13
Researchers documented a 24% increase in risk of women having a cardiovascular event and an overall 76% increase in risk of death from cardiovascular disease for each 10 ug/m3 of PM2.5 in the ambient air. Within-city risks were higher than the risk between cities suggesting the importance of local sources of particles, such as diesel vehicles.14
• Abnormal heart rhythms were found in healthy state troopers exposed to particles
In a 2004 study,15 particles were linked to significant changes in heart rate variability, ectopic (out of place) heart beats and increases in blood inflammatory markers within hours of exposure. 16
• Formation of blood clots (thromboses), have been documented in laboratory animals exposed to diesel particles.17

Recent data suggest that ultrafine pollutant particles (diameter
