ladder diagram for a garage door opener

I would like to see a ladder logic diagram for a garage door opener controlled by one pushbutton controlling both start and stop. Also, it must continue in the direction it was going after stopping and then re-starting.

Give him time. Once he gets the car out of the garage and onto the street, he's bound to come to an intersection at some point...

After solving the traffic light problem, he'll eventually make it to work. Let's hope he works in a 1-story building, else he'll be back with the elevator question in order to reach his office...
