“Yes, the yard can accommodate a car”
Again if it can then it can. As I said I havent seen his yard.
(Though worth noting, even if it CAN be used, arguably that isnt enough see the definition “and used by vehicular traffic to or from lands or buildings abutting a roadway” if it isn’t used (as evidenced by the beautifully manicured lawn then it isnt a driveway. Words have definitions “מַּעֲשָׂיו הָרָעִים” doesnt mean culture, “driveway” doesn’t mean lawn.)
