A few reasons you may want to clean up your entire driveway would be - once the snowpack freezes it will be harder to remove and may also take longer to melt in the spring. Even if you don’t clear up your whole driveway for a car you’ll still need to clear a path to walk to remaining way up to your driveway. If an emergency vehicle such as an ambulance or fire truck needs access to your house they will have a hard time reaching you in the event of an emergency.

most will recommend getting a snowblower or a plow if your vehicle accommodates one. Clear a path down your driveway for the car first. Then dig out the car and drive it off the driveway- either onto the street or just parked into a cleared section of driveway while you clear the area the car was originally parked in.

you’ll have an easier time finding a plow guy than you will finding someone to come snow-blow. Once you find a plow guy he will probably be able to let you know the best way for him to clear the driveway in regards to you moving your car so that will be a discussion you would have with him. It will depend on things like where you are on his plow route, where he is pushing the snow, and what kind of plow he is operating.
