If you have a big garage that allows you plenty of space to exit your vehicle, then this doesn't make sense. This feature is not for you. My parking spot is a narrow spot in a covered carport. It's uncomfortable to exit the vehicle when you're in the spot, without risking bumping the door into the next car over. The shared garage at my workplace is similar. My brother's home has a parking spot so narrow that you can't exit from the driver's side in an SUV due to a wall, so you have to climb out the passenger side. My parent's house has a garage used for storage, so there's lots of stuff piled around the car. And there's no direct entrance to the house (except via a ladder up to a hatch). All of these use-cases would be easier to park if you could get out of the car, and have it pull in and out (drive straight by the length of the vehicle) automatically. It's basically driven by the fact that the space needed to store a car is much smaller than the space needed to store a car with a door open. This is one of the best features I could ask for in a car, for me.
