my old design teacher once said to me "a Designer is an improver"
I think this statement is quite true, its very rare for someone to come up with a 'new' object for cars to roll on (a wheel as its most often known) but designers come up with new ways of shaping the internals of the wheel, wheel fixing, off-set, width and so on. this is design. (and often involved prototypes and testing to optimise this design)
getting a pair of calipers around a current wheel and reproducing it 100% like for like isn't really design is it.
I mean they could at least put some effort in and do an embossed logo or something like that surely...
before you beat me up, I'm using a wheel as an example here, I know people like to have a universal standard of fitment and we are restricted by tire dimensions too, but you get my idea.
