If the car expires, it will not be renewed or returned.

Query and display according to relevant information;

1. If the car fails to renew or return the car upon expiration, contact the car rental customer, negotiate the specific return date and ask for a new lease renewal contract. If it is not convenient for customers to renew their contracts in the company, they can confirm by fax or SMS.

2. If the customer delays again and fails to sign the renewal contract, the company can go to the door to learn about the customer's family according to the home address (contents in the household registration book), telephone number and other information involved in the original self-driving contract, and notify his family members to ask for cooperation.

3. In order to avoid this situation, it is suggested that car rental companies equip self-driving vehicles with GPS anti-theft system to accurately locate the vehicle position and driving trajectory. In case the customer does not return the car, the company can ask the GPS anti-theft system to cut off the oil and electricity, so that the customer can no longer use the car, and locate the car and forcibly retrieve it at the parking place.

4. If all the above methods are ineffective, you can report the case directly to the local police station.
