+| ignore_distance_from_lane_start | [m]  | double | This parameter ensures that the distance between the start of the shoulder lane and the goal is not less than the specified value. It's used to prevent setting goals too close to the beginning of the shoulder lane, which might lead to unsafe or impractical pull-over maneuvers. Increasing this value will force the system to ignore potential goal positions near the start of the shoulder lane, potentially leading to safer and more comfortable pull-over locations.                                                                                                                                                                                | 0.0                         |
