Once you can put a socket on the front of an impact driver, it extends
it's capabilities quite a bit.

Actually the first incarnation of this type of device was designed for car
use - to allow easy wheel nut loosening in event of a puncture, etc on the
road. They ran off the car battery and took any standard 1/2" drive
socket. I wonder if the cordless ones have enough 'impact torque' to do
the same job?

Not that they were needed if you remembered to grease the studs and not
overtighten the things in the first place.
