ha ha! i have a car that i can't go over speedbumps with, can't drive up kerbs or i scratch my wheels! wiper is the least of my worries!!
rear washer doesn't work anyway (and i can't be bothered to fix it!) so can only use it when it rains. i've never had a car with a rear wiper so it just confuses me tbh.
plus looking cool is more important....
and will force me to wash it...or buy wet wipes
