The best way of day-to-day driving is to minimise how many consumables you use. That's better for the environment, and more comfortable and cheaper for you. Here's a video of the main tips.
Eco-driving shouldn't compromise safety. Thus, "eco-safe". After all,  picking you out of a collision, then  caring for you or your passengers in hospital, plus  repair (or scrapping) of your car, each cost resources.
So ... make your eyes and brain do the work, so your hands and feet don't have to. That way there's less effort on your part, and less work by the car's engine, brakes, and springs … so less waste.
