Depends on how cold is cold. Since I don't have a garage, it would be really nice to have the car warmed up with seat heaters and steering wheel heaters on when remote starting it on frigid mornings. Not to mention having the windows defrosted.
I don't get the heated seat memory requirement. Usually I scale down to two bars after ten minutes, and turn it off by the time I've gone 20 or 30 minutes, so it wouldn't come on again anyway. Besides, I have a garage, and rarely need the heaters when leaving the house. Do people really leave them on indefinitely, without your butts getting too warm?
