Macnax, in a serious vein you have hit the nail on the head. Many of us are not mechanically inclined, and never had any intentions of tinkering with our cars. Most dealers won't even look at them let alone repair them.
So a small issue such as your wiper gets blown up way out of proportion and causes real angst for the owner.
If you look at the thread that I posted 2 weeks ago about not being able to start up my Karma, and thought I would need a new battery or have a permanently inoperable vehicle, you get an idea of what we are all up against. Think, that most owners don't want to come to grips with this problem, so therefore you see many more posts about Elon Musk and Tesla or Justin Beiber, than you do about the sustainability of our beautiful Karmas.
