If drag (air resistance) is ignored, the energy/fuel required to accelerate to a fixed speed is the same for any acceleration. However, if drag is not ignored, then energy does increase as acceleration increases. I did some math to find out myself on my SciLearn blog (see scilearn.blogspot.com/2008/07/dragging-energy.html). Also from a safety point of view, a slow acceleration is preferred. 2. Quote: "... you are using up extra petrol just to overcome wind resistance, in addition to moving your car forward." It's true that drag forces increases as speed increases, but technically speaking, moving your car forward at constant speed requires no energy. It's the drag forces and friction that burn all the petrol when you drive at constant speed. I also support the idea to pay attention to speed limits, for safety reasons. <strong>Mr Beagle</strong>: Yes, you're right, but sadly wind resistance cannot be ignored. Unless, someone can invent a device that is able to repel air particles from the car's trajectory? 1.

I never thought about the taxi driver angle. Hehe. <strong>Mr Beagle</strong>: Thanks! Nice take on the driving tips to save fuel! I never thought about the taxi driver angle. Hehe.

Mr Beagle: Thanks!

Thanks for sharing <strong>Mr Beagle</strong>: No problem Nice tips. Thanks for sharing

Mr Beagle: No problem
