1. On some special occasions, people will choose to rent or buy a mecha instead of a traditional wedding car. These mecha are generally worn by people, and the people who wear them generally have some training and know how to operate and maintain them.

2. When wearing a mecha to a wedding, people usually make some special designs to ensure the stability and safety of the mecha. For example, let the wearer step under the knee of the mecha's leg, let the wearer's feet support on the mecha, and put the wearer's arm on the elbow of the mecha to operate and control the mecha.

Therefore, the wedding mecha is worn by real people to replace the traditional wedding car.
