Provided is a method of manufacturing an automobile capable of automatic driving while recognizing and following a vehicle ahead. The method includes a first installation step of installing the following in a target vehicle-being-manufactured to make the target vehicle-being-manufactured capable of automatic driving: traveling parts including a tire and a wheel; a drive source that drives the wheel; a power supply device that supplies a power source for operating the drive source; a sensor that recognizes a vehicle ahead; and a controller that controls the drive source based on information acquired from the sensor such that the target vehicle-being-manufactured runs so as to follow the vehicle ahead, and a second installation step of, after the first installation step, installing an interior part in the target vehicle-being-manufactured while moving the target vehicle-being-manufactured by automatic driving so as to follow a vehicle-being-manufactured ahead of and adjacent to the target vehicle-being-manufactured.

A method of visually checking for alignment between an instrument panel ornament and a door ornament is provided. The method includes locating an enlarged head portion of an alignment tool on a top edge of the instrument panel ornament. The enlarged head portion includes a side measurement feature with a height for checking for a misalignment condition between the instrument panel ornament and the door ornament. It is determined whether a top edge of the door trim ornament is located within the height of the side measurement feature with the enlarged head portion resting on the top edge of the instrument panel ornament.

A welded steel part obtained by welding a first sheet with a second sheet, at least one with a coating of aluminum alloy. The welding uses a welding wire which, after melting and cooling, constitutes a weld bead connecting the first sheet to the second sheet and being part of said welded steel part. The respective peripheral edge of the first and second sheets are in a joggled edge type configuration in which the peripheral edge of the first sheet is arranged above, and on or near the upper face of an end portion of the peripheral edge of the second sheet which is extended by an inclined junction portion, at least one part of the upper face of the inclined junction portion delimits at least laterally with the edge of the peripheral edge of the first sheet a groove receiving the weld bead, the inclined joining portion extending by a welding portion in longitudinal continuity with the peripheral edge of the first sheet.
