How come with euro 5/6 vehicles the air is so bad all of a sudden.
God knows if everything was euro 2 and unleaded [emoji1787].
Plus the slower you go isn’t the air going to get more polluted as it will take longer to pass a certain point [emoji848]
The amount of pollution emitted is in proportion to the amount of fuel burned. Most cars use significantly less fuel per mile at 60mph than they do at 70mph, largely because aerodynamic drag is proportional to the square of the speed.
