Go too slow though and mileage goes down. At 60 mph my car gets around 25 mpg. At 1 mph it would get around 3 mpg.
That's because my car never consumes less than around 0.3-0.4 gallons per hour when the engine is running.

To answer your regenerative braking question: braking is inefficient by default, so just avoid tapping the brakes in situations where you could coast.
With regenerative braking, you'll never get back 100% the energy because of thermodynamics. There's always wasted energy any time energy is moved, transformed, stored, etc.
