Not to mention unlocking your doors if you screw up and have left the keys inside.

Actually Onstar uses regular old cell towers.. GRMS or something.. They use 3 or more cell towers to figure out where you are just like a GPS figures out your location via triangulation between three satellites.. So if you ever call them from a remote area and can only get signals from one cell tower, you better know where you are, because they sure won't..
FWIW... What you save on insurance for having an active theft deterant system (onstar, lo-jack, etc) will about pay for the cost of Onstar at $12 a month.. Least it does for me...
