    Why can't we use grass to run our cars?

    some people say we can make gas out of grass, grass grows so easily, so if it's true why don't we use it as our fuel source

    Actually we can use grass to run our cars... it is possible to make bio-fuels out of various types of "grasses", not your typical lawn clippings, but switchgrass to ethanol.
