As a point, Petrol's, though poisonous they are, they are not Cancerous, unlike diesels which provide sufficient exhaust fumes to cause the dreaded C word.
If people drove Bicycles like me this wouldn't happen, unlike some people I care about the environment. Even if you use a Hybrid, it's not the best. Fully electric is superb. I'm currently on the waiting list for an BMW i3, just because I'm better and more caring than most people.
