Killing speed kills planet

If the speed limit is reduced on certain secondary roads from 90kph to 80kph and I drive within that limit, I – plus, no doubt, thousands of others –­­ will be doing our bit extra to destroy our planet, because I drive a diesel-engined automatic vehicle.

When I drive at 85kph my car is in overdrive. Dropping to 80kph will mean I will have to drive in a lower gear, which means higher revs and more pollution.

Why don’t the politicians look at all the options before taking decisions that have not been properly thought out?

Modern diesel engines are now cleaner than petrol!
