Even if the tenant has a car, which I understand to be the case, the landlord has committed to offering the tenant one spot in the shared two-spot parking area. (The tenant's desire to reinvent the two parking spots into a single space is not going to fly -- even he admits that there's room for two cars and that he could share the spaces with another tenant.) He is entitled to "the use of one (1) space in the driveway to the west of the building, which consists of two (2) and only two spaces" -- as long as he gets that, there's no breach.
