The InstantRide Driver Relationship team wants to analyze the travel information of the low rated drivers. You will need to provide them with all the travel information of the drivers with the average rating lower than 4. The team wants to get in touch with the travelers and analyze their feedback.

Each row contains details of a specific trip, organized under the following columns: 1. **TRAVEL_ID**: A unique identifier for each travel record. 2. **TRAVEL_START_TIME**: The date and time when the trip started, formatted as YYYY-MM-DD HH:MM:SS. 3. **TRAVEL_END_TIME**: The date and time when the trip ended, formatted similarly. 4. **TRAVEL_START_LOCATION**: The address or location where the trip began. 5. **TRAVEL_END_LOCATION**: The address or location where the trip ended. 6. **TRAVEL_PRICE**: The cost of the trip in currency units. 7. **DRIVER_ID**: A unique identifier for the driver assigned to the trip. 8. **CAR_ID**: A unique identifier for the car used in the trip. 9. **USER_ID**: A unique identifier for the user who booked the trip. 10. **TRAVEL_DISCOUNT**: Any discount applied to the travel price, where available; otherwise marked as NULL. For instance, travel ID 5004 started on 2019-10-02 at 08:44:28 and ended at 09:15:28, starting from 9060 Mill Lane and ending at 27 Main Road, with a travel price of 30.49.
