KillerBee370,
Life is a matter of one's perspective. I still drive around with people who see a yellow car, even an a exotic, and say, "Boy, he must have gotten a great deal on that one!"
If I recall Pushing Tin resides in Oregon, which is not a self-serve gas State, he is probably tired of explaining how to open the fuel lid to the attendant versus simply having a means of popping it open where the attendant can see they it is open.
Although I would not have need for rear window wiper those who live in areas of inclement weather (and I can definitely see having one in Japan) value such a wiper. Northwest States have pissy rain, that is like a constant heavy dew; this type of rain coats a window versus shedding.
