Not only for reversing. I allways wondered how bus-/lorrydrivers can run
along the kerb so close without constantly hiting it - until I did the
license myself. Having those massive mirrors on both sides makes it
quite easy to maneuver an up to 15m bus or 18m bendy: you see the whole
length and height of the bus and _that_ makes not hitting the kerb
possible. Though the problem reversing is the masive blind spot you have
behind (unless equipped with a camera). I sure miss larger mirrors on my
car (and the retarder).
