Sometimes, manufacturers or all stripes, kinds and sectors offer innovations that aim to improve nothing. These key cards or retracting door handles are two examples. Why? is the big question. "drag coefficent" is often the bright-eyed answer. Or "why not?" is the smug answer.
I wonder what one loses by leaving a convention, approchable and intuitive door handle in its place? In the case of this valet card, how does the valet know that he has to do touch it just so? Where does he hang this 'key' on his board where he hangs all other keys? Do I owe him a bigger tip because he had to figure all this out while I walked away on my way to the Legal Seafood and he reminds me when I come back and ask for the car?
