Technique is great, but what if you want to just hop in the vehicle and drive reasonably?
I prefer to rely on mods more. Besides, if someone else drives the car, those fuel saving devices are in place.
Best of all, I suppose, is to start with a great platform.
I'll admit, I had the biggest jump with extreme technique, but it wears on more than just the longevity of vehicle components. I'll still engine-off coast now and then -- but not as often, for example
