Isn't the average cheapass (like me) who they are marketing to? Additionally from what I have seen it is well established that this car's purpose it to be a utility and stand solely on its use, not be a fashion image or statement via image. Correct me if I'm wrong.
In the beginning yes, but overall they would want almost every household to have one (goal of all automakers). With that few people in America are cheap asses. Most have a ton of cc debt and living pay check to pay check. At the same time they have a brand new vehicles.
This is about sales. Its not about us cheap asses that would buy it. They don't have to market to us much. A company wants to strive to expand their market without alienating their core.
IMO the safe way would be to put the reservoir in there. It won't cost them, it will cost the buyer......about $2 extra dollars. What is that when you are spending almost $7k on something.
Also if it's sole purpose is utility, then why have door panels, spend time on a gauge cluster or the body? A pure utility vehicle is like a willy's jeep. Even people on this forum are asking about power steering and heated mirrors and other "luxury" items. Again this is all to expand the market.
