Why no remote unlock?

I use my plane for family transportation. So the wife and kids don't
see a lot of difference between running out to the plane to go to
Mexico vs. going out to the car. So when the family runs out ahead and
we have the car I hit the remote unlock. The other day my wife asked
why the plane doesn't have a remote unlock. When you think about it;
why not have the same ease-of-use items in the plane as the car.
