Modern cars should be equipped with a catalysator, making the majority of pollution to be Co2, worsening the global warming.
To some extent heavy metals are being distributed in the air by the wheels in heavily populated areas.
This can be greatly improved by limiting traffic in heavily populated areas. Trump removed such a rule from New York City recently for reasons I can not comprehend.
Many european cities have improved air quality successfully and hence increased life expectancy by limiting car traffic.
The majority of air pollution of particles however, is caused by the industry (the companies making those cars, among others).
In fact, you are a worse polluter of the earth today if you buy a new Tesla than if you kept driving your 1980s gasoline car due to the amount of pollution created by producing a single vehicle.
Particulate matter is still a huge problem, mainly produced by tires and break pads, but also road abrasion. In terms of pure engine exhaust, catalysts don't do much here, you'd need a particulate filter, which not all cars have. So, cars still a problem wrt cancer, as particulate matter is carcinogenic.
European cities were especially bad because the EU pushed diesels while having significantly less emissions controls than gas vehicles until the mid 2000s. Most of the vehicles impacted by ULEZ are those same diesels.
