No, the driveway wouldn't count. Texas doesn't define burglary by property boundaries; you have to enter a "building" or a "habitation", and a habitation must be a "structure" or a "vehicle".
Are you sure that doesn't qualify on the basis that it is the curtilage of your home? Often this counts as "in your dwelling" because it's in your private space that immediately accompanies the dwelling.
Is this true in any context other than a potential fourth amendment violation by an agent of the state?
