The car rental process was smooth. The staff just asked if I wanted to upgrade the car model or buy additional insurance. I declined, and they quickly prepared the contract. I was then directed to the parking lot where a staff member brought a similar type of car. The rental process was smooth. Later, in Los Angeles, I accidentally bumped the front bumper. When I exchanged the car, the staff noticed I had insurance, making the return process smooth. Therefore, having insurance is quite necessary. Additionally, if you're not far from the airport, they can arrange a driver to drop you off at your destination for free!
