One of my family members, who live on 5th avenue in NY, have a seperate parking garage across the street from their building. They pull up to the curb, get out of the car, and one of the attendents drives it into the garage. When they need the car again, they tell the doorman, who calls over to the garage, and within two minutes it is running/waiting out front for them.
They rarely drive their cars. 99% of the time, they just sit in the garage. Most of the time they are being driven somewhere by somebody else.
