DRIVEN to save gas.
Brian Morris drives like your grandmother -- but with a purpose. Before he starts his engine, he checks the stoplight down the block, so he can get to it as it turns green. He eyes approaching traffic, too, and waits for a gap, so he can merge without delay. He lets out the clutch the instant the engine catches, and then slides the shifter of his Toyota Yaris out of first gear, briefly through second and into third about two revolutions per minute above the speed at which the engine would lug.
