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 & brain do the work, so your hands & 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.
