If the road is flat or has a small rise then I don't change down but I usually stand on the pedals when the lights turn to green to get up to speed quickly and it's good training for the legs IMO.!!!!!!!!!!!!!!!!!!!!!!!!!!
I was actually taught in my driving test specifically not to do this - the engine will only stall if you come to almost a complete halt and then try to pull off, otherwise being at lower revs isn't a problem. According to my driving instructor, driving in a higher gear than the speed needs (e.g. 4th or 5th gear for 30mph) actually means the car uses less petrol because you're using less revs... thereby saving both money and the environment, hurrah. Also sparing the gears on the car.
Often when I'm slowing down to a junction I just disengage the gears completely and coast in on the clutch.
Of course if you want to pull away, manoeuvre or suddenly accelerate you then have to change, but if you're just driving along normally and aren't intent on overtaking people, then that's how they teach it now... or at least when I did my test in 2009!
Modern electronic injection does not any fuel if foot is off the throttle and coasting in gear.
You are using fuel when clutch is in as engine is running.![]()
If your foot is off the throttle and the clutch is in, why is the car giving you any more fuel than it would be if the gear was engaged?Modern electronic injection does not any fuel if foot is off the throttle and coasting in gear.

Modern electronically triggered injectors shut down completely when you lift your foot off until the ECU detects that the revs have fallen to tickover then they start to supply fuel again, unlike older systems and carburettors.If your foot is off the throttle and the clutch is in, why is the car giving you any more fuel than it would be if the gear was engaged?
Anyone else noticed that some modern car engines have very little inertia, so engine braking is ineffective. I wish they'd get on and equip more with regenerative braking!
Twice as tall as the distance from top to middleHow big is top gear, in this context?
Yes, I don't enjoy trying to pull away in a gear that's comfortable at 17mph
