automatics decrease fuel efficiency

Wow. I didn't know that. (I would have assumed that deciding which gear is most efficient at a given speed was something machines would be better at than humans.) What's it good for, then?

Automatics are easier to use and probably safer, since both hands can be kept on the wheel. The fuel efficiency reduction is (I think) mainly because of the energy used in the pumping of hydraulic fluid, not switching gears poorly.
