Hello, welcome to OSM! Please do not removed driveways if they do exist on the ground. Driveways are valid data and removing them in incorrect. Removing valid data is actually considered vandalism. They are not redundant, as you have not replaced them with anything. 

If something exists on the ground it can be added, if something is "needed" or not is not a valid reasons to remove it as long as it exists and is mapped correctly.
