Maybe there is a case to be made against people over a certain age being allowed to drive, but then it depends on the person, Stirling Moss is still a great driver and he's in his late 70s, but there are some old people who really shouldn't still be driving. So is it really true that older American drivers favour the big Cadillacs and Lincolns? Apparentely Cadillac had an image problem as a maker of old mens cars until it launched the Escalade SUV/pimpmobile.
