I have to spend a lot of time in my car, often behind vehicles pushing out nasty petrol and diesel fumes. Does this put me at risk of getting respiratory problems in the future?
This, [respiratory..] is why cyclists in e.g. London tend to wear filter masks. Maybe car drivers should too. And pedestrians, dogs and horses. And why don't they produce and encourage a cheap alternative like electric scooters? Because it's not about cars it's about selling petrol.
