If the sensors are located on each side of the garge door track at the bottom you cant hesitate to enter the garage. One side sensor sends an infared beam to the other side of the track that is just a reflector to send the beam back. Your tires break the beam keeping the door open. But once your tires past the beam the circuit is complete again and the countdown delay starts. If you stop for some reason that countown still goes because there is nothing breaking the beam. Sounds like the delay needs to be adjusted or you need to stop looking at chicks when you enter the garage
Either way sorry to hear that.
