I use it occasionally. It's usefgul when you can clearly see what the nearest unexplored warp point is (ie it's in the same system) but you can't be arsed to press "w" and then click the WP. Much easier to just hit "e" and let the computer figure it out.

It's like using the "r" or "s" key to send your ships back to your homeworld even though they don't need repair/ resupply.
