Don't do this if your power brakes run on engine vacuum!  Also don't do 
this if you drive a "big" truck -- semi or whatever.  The DOT doesn't 
allow coasting -- it'll get you a ticket if you get caught -- idling 
engines might not have enough power for the power steering and might 
not keep the air brake reservoir at full pressure.

Push the "resume" button on your cruise control -- it'll do this for 
you.  I've worked with my truck driver employees that are used to 
gasoline engines -- when driving a diesel they should work their way up 
through the gears as quickly as possible and use the fuel to increase 
speed of the vehicle.

Or the many friction interfaces inside the drivetrain.
