Down south I think it's mostly airspace - get the student flying at 2000 ft and he'll never wander into the London TMA (well, apart from those bits that go down to the surface!). I guess it's habit forming. Under the TMA I usually plog 2200ft to avoid all the people at 2000ft. When there's more sky to play with I usually fly quadrantal levels around 4000ft.
