A large car is comfortable and safe, but it’s also harder to find a parking place for it on the street.
Build the car so that it can contract before parking.
You don’t remember where you parked.
Have a small remote controlled device (dedicated or using a smartphone) that when activated, raises a visible signal on top of the car (a white flag or blinking extended telescopic “stick.”)
You go into a large multi-level parking garage, and would like to know where are the free spaces.
Each car entering is given a reusable parking card with dual functionality: use it to pay and exit, and it will show you on a map (a small screen) currently where you can find empty spaces to park, and where you are. It’s a live map guiding you to the available spaces.
