In a curb-to-curb service, the driver waits for you outside the door to pick you up. It is like taxi and cab apps where the car waits at the given location, in this case, outside your home. Once they have reached the location, you make your way into the vehicle. Then they drop you at your destination and drive away.
The driver’s responsibility in this service is limited to dropping you at your destination. It works great for people who either have a friend or relative accompanying them or someone already waiting at the destination.
