Tho remind me never to travel behind or beside (in the other lane) the white car with no roof racks but laden with SUPS and tie downs passed through the roof on the open highway at 110 in strong winds....it may be fine for short commutes at 60km/h but that is an accident waiting to happen..getting wind blown across lanes...MY Commododore fully laden with family, boards and surf gear would be close to 2 tonnes (maybe a slight exaggeration) and in very strong winds you can feel it wanting to cross lanes...A small car like that would act like a kite IMHO.
