Driving on the motorway and around town I see a lot of wastage of fuel
acceleration only to then brake sharply
leaving a motorway people accelerating on the slip road - when the slip road is designed to naturally slow a car down to a stop because its often an upward slope
Excessive speed to then be at the traffic lights just in front of me, so no gain but fuel wasted. Or excessive speed on the motorway which will burn literally 25% more fuel
No point in complaining about rising fuel prices of 12p a litre when drivers are wasting far more than that with the way they drive
